Not only do you travel to an exotic country, you also meet like-minded people, and at the end of it all you have something to put on your CV to impress employers with. But did you ever stop to think about how great it is for the people on the receiving end?In this context, Daniela Papi has a point---foreigners rushing heroically to volunteer in a country they’ve never heard of are unlikely to make a difference. But turning volunteering camps into classrooms, as Papi seems to advocate in her article, risks throwing the baby out with the bath water by putting people off of volunteering. Rather, learning should be a natural part of the experience, and the key to creating such an environment is positioning everyone as equals. In order for that to happen, volunteers need competent leaders who create an environment of equality:When, a few years ago, I joined a group of international volunteers to help a small farming community in the Swiss Alps, we were all quite ignorant about the local conditions. But thanks to our group leader, it was both a helpful project for the locals and a fun and eye-opening experience for us.Before we had even traveled (at our own expense) to the mountaintop village, our group leader had spent time with the villagers preparing the project to make sure it would be of benefit to them. She arranged for us to help in different areas, ensuring that we always worked alongside locals rather than for them. It was never "us" and "them", but always "we", like a big family. As a result, conversation flowed and we learned a great deal just by casually talking to the locals as we worked.At the end, we left with a deep appreciation for the labor of love that goes into producing the food we eat every day一一an appreciation we could treasure ourselves and share with our peers.Volunteering isn't about saving someone's life, or even about changing it. It's about touching a different world and reminding ourselves that there is much, much more to life than the daily routines we take for granted.With thatknowledge, maybe, just maybe, we can go on to really change the world.By Lukas Thibaut【1】From Paragraphs 1 and 2, we can learn that____in international volunteering.A.foreigners are not welcome in some local communitiesB.blind enthusiasm fails to make the experience rewardingC.the author agrees with Daniela Papi's opinionsD.international volunteering is actually a poor approach to education【2】The underlined word "that" in Paragraph 3 refers to___,A.a natural part of the experienceB.the learning of volunteeringC.creating such an environmentD.positioning everyone as equals【3】What contributed to the success of the author's volunteering project in the Alps?A.The volunteers were quite familiar with Swiss farmers' lives.B.The volunteers worked in areas separated from the locals.C.The group leader ensured that the project would be beneficial to both sides.D.The group leader ensured that the volunteers got to know the local conditions.【4】From the author's viewpoint, what should international volunteers avoid?A.Placing themselves above the locals.B.Taking food for granted.C.Disrespecting others' labor.D.Being proud of volunteering.【5】Which best describes the author's attitude toward international volunteering?A.Objective. B.Doubtful.C.Disapproving.D.Supportive.2.Phantom vibrations-the phenomenon where you think your phone is vibrating but it's not-have been around since th e mobile age. Today, they’re so common that researchers have devoted studies to them.For Valerie Kusler, who works on a cattle farm, the feeling is complicated by the cows“The cows’moo is very muffled, it kinda sounds like…errrr,”she says.“So that's very similar to what my phone sounds like when it vibrates on my desk or in my purse.”Other people may not confuse cows for their phones, but research shows phantom vibration symptom is a near-universal experience for people with smartphones.Nearly 90 percent of college undergraduates in a 2012 study said they felt phantom vibrations. The number was just as high for a survey of hospital workers, who reported feeling phantom vibrations on either a weekly or monthly basis.“Something in your brain is being trigg ered(触发)that's different than what was triggered just a few short years ago,” says Dr Larry Rosen, a research psychologist who studies how technology affects our minds.“If you'd asked me 10 years ago, or maybe even five years ago if I- felt an itch beneath where my pocket of my jeans was, and asked me what I would do, I'd reach down and scratch it because it was probably a little itch caused by the neurons firing(神经元刺激),”he says. Now, of course, the itch triggers him to reach for his phone. Rosen says it's an example of how our devices are changing how our brains process information.“we’re seeing a lot of what looks like obsessive behavior. People who are constantly picking up their phone look like they have an obsession. They don't look much different from someone who's constantly washing their hands.I’m not saying that it is an obsession, but I’m saying that it could turn into one, very easily," Rosen says.While 9 out of 10 participants in the study of college students said the vibration feeling bothered them only a little or not at all, Rosen still recommends backing away from our phones every once in a while to keep our anxiety levels down.“One of the things I’m really adamant about in spite of being very pro-technology, is just away from the technology for short periods," Rosen says."And by short periods. I mean; maybe just 30 minutes or an hour.”【1】According to the article, phantom vibrations_____.A.are mainly caused by neurons firingB.affect people mostly working on farmsC.help our brains better process informationD.started troubling people in recent years【2】The underlined word "adamant" in the last paragraph probably means_____.A.curious B.determined C.satisfied D.cautious【3】It can be concluded from Larry Rosen's research that_____.A.phantom vibrations could probably result in obsessive behaviorB.the use of smart phones has completely changed the way our minds workC.most people feel uncomfortable when they experience phantom vibrationsD.hospital workers are more likely to suffer from phantom vibrations than students【4】According to Larry Rosen, the most effective measure against phantom vibrations is to_____.A.move to a quieter neighborhoodB.stop using smartphones in poor conditionC.take a break from using smartphones occasionallyD.keep a close watch on your anxiety levels3.CURRENCY• New Zealand dollars($)LANGUAGE• English, Maori and New Zealand S ign LanguageMONEY• ATMs are widely available, especially in larger cities and towns,credit cards accepted in hotels and restaurantsVISAS• Citizens of Australia, the UK and 56 other countries don't need visas for New Zea(length-of-stay vary).MOBILE PHONES• European phones will work on NZ's network, but not most American or Japanese phones.• global roaming or a local SIM card and prepaid account.DRIVING• Drive on the left; the steering wheel is on the right side of the car(…in case you can't find it).When to Go• HIGH SEASON (DEC-FEB)Summer: busy beaches, outdoor explorations, festivals, sporting events.Big-city accommodation prices rise.High season in the ski towns is winter (Jun-Aug).• SHOULDER (ATAR APR)Prime travelling time:fine weather, short queues, kids in school,warm(ish) ocean.Long evenings supping Kiwi wines and craft beers.Spring (Sep-Nov) is shoulder season too.• LOW SEASON (MAY-AUG)Head for the Southern Alps for some brilliant southern hemisphere skiing.No crowds, good accommodation deals and a seat in any restaurant.Warm-weather beach towns might be half asleep.• Auckland International AirportAirbus Express-24-hourShuttle Bus一一24-hour door-to-door servicesTaxi一around$70; 45 minutes to the city• Wellington AirportBus——Airport Flyer from 6 am to 9.30 pmShuttle Bus-24-hour door-to-door servicesTaxi-around$30;20 minutes to the city• Christchurch AirportBus一一City Flyer from 7.15 am to 9.15 pmShuttle Bus一一24-hour door-to-door servicesTaxi-around $50;25 minutes to the cityDriving Around New ZealandThere are extensive bus networks and a couple of handy train lines crisscrossing New Zealand, but for the best scenery, flexibility and pure freedom it's hard to beat piling into a camper van or rent-a-car and hitting the open road.

Even more are expected to tune in to this year's contest, which kicks off on June 12th with a match between Brazil and Croatia in Sao Paulo. Brazil are the runaway favourites to win the tournament, with bookmakers offering odds of less than three to one on the home team winning the championship.Many experts agree that the country will benefit from a strong home advantage, as local crowds roar on the Seleqao.How much does playing on home turf fealty affect a team's performance?Sports scientists have come up with all sorts of theories to explain why playing at home helps. In 2007 a study investigated the influence of crowd noise on referees in the English football Premier League. It showed that some were more likely to flash yellow cards and award penalties against touring players than the hosts, because they relied on the split-second rise in the home crowd's roar as a reminder to determine if a tackle deserved punishment. In the most recent season of the Spanish football Riga, two-thirds of all penalty kicks were awarded to the home team.In the latest English football season, the top 20 clubs enjoyed a home success rate of 50%, while their victory rate on the road was 32%. In 12 of the past 19 World Cups the host nation has made it to the semi-finals and six times it has gone on to win. The effect can be seen in other sports too. A Before the start of the London Olympics in 2012, UK Sport, a government agency, studied the results of more than 100 big tournaments across 14 Olympic sports. B As it turned out, Britain bettered its 2008 performance by winning 18 more medals(10 of them gold), an improvement of 38% . C At the Beijing games, China won 59% more medals than it had done atthe 2004 Athens games. D Russia topped the medal table in Sochi:in the previous winter Olympics it had come sixth.Given these numbers, it is not surprising that teams have poured money into maximizing their home advantage. For example, Brazil has spent a considerable fortune on, if somewhat leisurely, a programme of stadium construction and renovation. In all its home advantage is worth the equivalent of a 0.6-goal headstart in every match, according to Goldman Sachs, an investment bank. Like most others, Goldman predicts that Brazil will triumph this year. Other countries' fans will have to hope for a miracle-and perhaps bid to stage the Cup on their own home turf next time.【1】What does "some" in Paragraph 2 refer to?A.Crowd noises.B.Referees.C.Touring players.D.Host players.【2】Put the following sentence in the most appropriate place marked A, B, C, or D It predicted that the London home advantage would boost Britain's medal haul by as much as 25%.【3】What can be inferred from the passage?A.Fans may raise their noise levels to cheer their teams up.B.Brazil will win because of its strong ability.C.It is a waste of time and effort for countries to hold sports games.D.The visiting teams have a good chance of winning.四、其他Socrates-an ancient Greek philosopherSocrates was an ancient Greek philosopher, who helped to shape Greek beliefs. The ideas he created are present in our culture today.Socrates was a person full of curiosity. From the time he was a young man, Socrates searched for wisdom and truth. He gained wisdom by asking questions. Many people in Athens thought that they had answers. Socrates asked them questions and argued with them about different topics. He did not think they had the knowledge they claimed to have.Socrates challenged false ideas people had about things like justice, love, or courage. He would break down the ideas people held. Then he built new and more accurate ideas. Socrates felt that this was what philosophy was all about. Since then, many great philosophers have used this method to find truth.Throughout his life, Socrates showed no interest in money. He was also not interested in material items. Socrates would allow groups of men to listen to him speak. And he would never take money from them. He always wore the same clothes whatever the season. Socrates argued that his life was better because he had no material wealth.He felt he enjoyed his food more. He said he was stronger and healthier because he was not affected by the weather. He believed happiness came not from having more but from wanting less.By the end of the fifth century B.C, Athens was not a great city anymore. Politicians betrayed Athens. Socrates had made many people angry over the years. He had always expressed his opinions when he thought laws and policies were wrong. Athens had a new group of political leaders in power, who didn't want to hearSocrates’comments about them. They thought Socrates had a bad influence on the young people of Athens. Socrates was also accused of not worshipping the right gods. Charges were brought against Socrates. The politicians wanted to condemn Socrates to death. Socrates’friends told him to leave Athens. They thought this was the only way for him to save his life. Socrates refused. He did not behave as most people in his situation would.Socrates said that he had always lived by the rules of Athens and he would continue to do this. He insisted on standing trial for his "crime". Socrates knew he was not guilty of anything. The reason why he was charged was because he was different from others. Although people respected him, he also had made many people angry, so the jury(陪审团)said Socrates was guilty.When faced with the death penalty, a person could leave Athens forever. Most people chose to leave rather than die. Socrates was not like most people. Instead of telling the jury that he would go, he told them he deserved a reward. Socrates believed he had done a great service by making people think. Socrates said that he tried to "persuade every one of you not to think of what he had but rather of what he was, and how he might grow wise and good." The jury did not change its mind. Socrates was executed. He died when he drank hemlock, which is poisonous.Socrates was the first great Greek philosopher. He also helped to shape other philosophers that came after him. Plato, who got his start by studying with Socrates, and Aristotle, who studied with Plato, also changed Western civilization. Asking questions to discover the truth is still practiced today. And schools even today still teach this method to students.Socrates--an ancient Greek philosopher五、书面表达Passengers are banned from eating and drinking on subway trains, according to a regulation recently released by Nanjipg's transport authorities·Under the new rule, passengers should not eat or drink in subway cars, though they are still allowed to eat at the stations. The Metro operators will first warn and then fine violators between 20 yuan to 100 yuan.The regulation caused a strong reaction of the whole society and started a heated discussion.Supporters say that passengers who eat on trains annoy others with unwanted smells and make messes with spilled food or beverages(饮料). However, some others believe otherwise, saying that the fast pace of big cities squeezes people's time and makes it hard for them to -get a proper meal.

In the near future, electric power and electron will make electrical source technologies become more mature, economic, practical, high efficiency and high-quality combination of electricity.History about electronicsThere can be no doubt that 1900s is remembered as the electronic century. Of course there have been other great advances, in medicine, in transport, in science, in commerce, and many other fields, but where would they have been without the instruments and devices that electronics has provided? How would you see a 3D virtual reality image of your beating heart with no electronics? How would you get money out of the bank on a Sunday night without electronics? Would you go to a pop concert that had no amplifiers, large screens or lighting effects? Don’t you would rather watch TV –there would not be any.Electronics in the early 20th century started thriving at a greater speed unlike the pre-20th century developments. The radio invented by the Italian genius Marconi and the work of Henry Hertz opened the road to further discoveries and inventions. In the first decade the new thing that was welcome to the technical would was the vacuum tube. The vacuum tubes at that time worked as a miraculous component for the radio devices.The invention of the television was a miraculous thing for the mankind. It was revolution in both communication technology and also for the world media. The distances between the continents did not seem to be far enough. The credit goes to the British engineer John Logic Baird who followed the footprints of Marconi and tried to send the same way as the speech. After a long experiment he found that a series of static pictures if sent within a small interval of time in between them, seem to be moving.The real electronics what it is called today was actually started after the discovery of the transistor effect. Transistor opened the road for the electronics and more importantly it opened the road for the computing world. Computers of various types started hitting the market and the research works got a boost.Some other problems were also there like the assembling of the electronic components on a single mother board. Jack Kilby in Texas Instruments found a very nice solution. He suggested to throw away all the wires and tried to connect the resistors, capacitors and transistors on the same piece of wafer internally. Surprisingly his ideas worded and gave birth to the integrated circuit industries.Introduce to Some CoursesAs a student majoring in the electronic technology, you will study many courses such as:1.

For most applications, The most effective way to remove ripple is a combination of a capacitor-input filter used with an IC regulator. In general, an IC (integrated circuit) is a complete functional circuit constructed on a single, tiny chip of silicon. An integrated circuit regulator is an IC that is connected to the output of a rectifier and maintains a constant output voltage (or current) despite changes in the input, the load current, or the temperature. The capacitor filter reduces the input ripple to the regulator to an acceptable level. The combination of a large capacitor and an IC regulator is inexpensive and helps produce an excellent small power supply.The most popular IC regulators have three terminals; an input terminal, an output terminal, and a reference (or adjust) terminal. The input to the regulator is first filtered with a capacitor to reduce the ripple to <10%. The regulator reduces the ripple to a negligible amount. In addition, most regulators have an internal voltage reference, consisting of a zener diode, short-circuit protection, and thermal shutdown circuitry. They are available in a variety of voltages, including positive and negative outputs, and can be designed for variable outputs with a minimum of external components. Typically, IC regulators can furnish a constant output of one or more amps of current with high ripple rejection. IC regulators are available that can supply load currents of over 5 A.1.IC card technical characteristicalong with microelectronic technology unceasing development, specially 1μm following memory chip manufacture craft breakthrough and mature, causes the entire IC card technology to present the more and more formidable vitality.1.1Simple, the stable read-write performanceRegarding the magcard, the linearity card, the light card, its information in the medium distribution is the plane. Therefore, when by read-write card in information, the card machine magnetic head and the light telegram heading all must the relative card carry on the reciprocal motion. Satisfies this transmission request the mechanism quite to be without doubt complex, thus increased the card machine failure rate greatly. Moreover, because the magcard, the linearity card or the light card carry on the data access directly, but is needs through the magnetoelectricity transformation or the photo electricity transformation, transforms magnetism signal or the light signal the logical level signal. Therefore the signal transformation part further increased the card machine electricity part complexity. Regarding the IC card, its information card, its information storage is based on the semiconductor electric circuit. The information may understand three-dimensionally for in the medium distribution. In the use the card machine and the card direct contact, and maintains both relatively static, thus does not need the complex mechanical drive structure. On the other hand the IC card andbetween the card machine carries on the logical level wigwag directly, does not need the clear signal type transformation. This causes the card machine which the card machine mechanism and the electric circuit composition relative other cards plant is greatly the simplification, this directly will cause the machine cost to drop, the maintenance cost will reduce, the machines and tools use will be stabled reliably.1.2 data storage stableGeneral magcard signal storage time is approximately 1~2 years, and needs to duplicate unceasingly renovates, maintains the data not to be able to decay. The card read-write number of times also is restricted in several thousand next best, more uses will not be able to guarantee the data the stability and the reliability. Uses in the IC card the semi-conductor memory being able to guarantee the data the maintenance time above 10 years, even can achieve for 100 years long time. This enables the card in to escape the net in the situation to use, also can guarantee the data the authenticity and the reliability. Simultaneously also reduced the worry data possibly to change or the loss carries on the revolution and the backup work. On the other hand, the IC card memory cell may duplicate scratches reads in the number of times to reach generally 10,000 times, even reaches above 100,000 times. Not only this directly increased the card repetition use ability, moreover reduces likely the magcard such many times to send the cost of capital greatly which the card brings.1.3 large capacity data storage abilityMagcard data ability are generally most only then more than 300 (light card although reserves may be very big, but because is read-only, thus its application is restricted). However, present commodity IC card storage capacity: The memory stick, may reach the 4M position, the logical encryption card, may reach the 16M position, but regarding brings the CPU smart card, the storage capacity to reach the 64K byte, also may affirm, along with the Semiconductor Technology development, its capacity also will become the position growth every year. Not only this enables the IC card to apply in the memory picture, the fingerprint, the sound wave, regards the net grain and so on some need large capacity information in the biology trick recognition project, but also was " card multipurpose " has provided the bigger capable of extension.1.4 Many kinds of encryption technologymeasure in the magcard, the bar code card or the light card information needs to carry on certain transformation to be able to distinguish, but they forge and the malicious interpolation attack lack the enough resistance energy actually facing the duplication. Regarding the IC card, may use many kinds of encryption technology measure: (1) hardware logic encryption way: Namely uses the semiconductor password which cannot be read to save, enables the password comparison operation only in the chip interior to complete voluntarily. (2) common software logic encryption way: Namely uses the characteristic character mix code either uses Canada to examine the glyphomancy verification with clearly marked price processing or uses the scrambled text code directly, all may quite conveniently enable the information which in the card saves to achieve the good encryption performance. (3) strict software encryption way: Brings the CPU intelligence IC card through the choice, in the use card the CPU operational capability and the monitor routine, the international general each kind of encryption algorithm (for example DES, RSA and so on) will apply in card encryption processing, will enable the IC card the safety performance to achieve the quite high level.1.5 intellectualized processing and the resolution capabilityLight discusses is the magcard, the light card or the bar code card, all is the non-intelligent passive operating mode. But intelligence IC card, not only can on owninitiative send out the order request to the interface equipment, the distinction interface equipment validity, as well as discrimination interface equipment function and jurisdiction, moreover has the voluntarily operation and handling ability.1.6 each kind of compatiblefunction the IC card itself substrate contour conforms to the international standard ID-1 size, also the Khaki material is same in the magcard, therefore, attaches on the magcard or the additional painting bar code on the IC card substrate, may satisfy the magcard application and the bar code card application.1.7 good comprehensive cost benefitat present, the IC card average monolithic cost is approximately more expensive than the magcard 3~5 times. But the comprehensive IC card system comprehensive cost benefit, not difficult to see it to have the strong competitive ability.In summary, IC card this newborn product compares with other Khaki product, has the unquestionable technical superiority. Along with the technical development, this kind of superiority further will also develop and the expansion. Therefore in the next Khaki product application, will substitute for other cards with the IC card to become the next development the main characteristic and the inevitable trend.INSTUMENTATIONAMPLIFIERSOne of the most common problems in measuring systems is the contamination of the signal from a transducer with unwanted noise (such as 60 Hz power line interference ). The transducer signal is typically a small differential signal carrying the desired information. Noise that is added to both signal conductors in the same amount is called a common-mode noise. Ideally, the differential signal should be amplified and the common-mode noise should be rejected.A second problem for measuring systems is that many transducers have a high output resistance and an easily be loaded down when connected to an amplifier. An amplifier for small transducer signals needs to have a very high input resistance to avoid this loading effect.The solution to these measurement problems is the instrumentation amplifier (IA), a specially designed differential amplifier with ultra-high input resistance and extremely good common-mode rejection as well as being able to achieve high, stable gains. Instrumentation amplifiers can faithfully amplify low-level signals in the presence of high common-mode noise. They are used in a variety of signal-processing applications where accuracy is important and where low drift, low bias currents, precise gain, and very high CMRR are required. CMRR is often specified in decibels (dB), which is designated as CMRR’. IAs are available with CMRR’s of up to130 dB.An instrumentation amplifier is a differential voltage-gain device that amplifiers the difference between the voltages existing at its two input terminals. The main purpose an instrumentation amplifier is to amplify small signals that are riding on large common-mode voltage. The key characteristics are high input resistance, high common-mode rejection, low output offset, and low output resistance.TROUBLESHOOTINGAs a technician, you may encounter situations in which an op-amp or its associated circuitry has malfunctioned. The op-amp is a complex integrated circuit with many types of internal failures possible. However, since you cannot troubleshoot the op-amp internally, treat it as a single device with only a few connections to it. If it fails, replace it just as you would a resistor, capacitor, or transistor.In op-amp configurations, there are only a few components that can fail. Both inverting and noninverting amplifiers have a feedback resistor, Rf, and an input resistor, Ri. Depending on the circuit, a load resistor, bypass capacitors, or a voltage compensation resistor may also be present. Any of these components can appear to be open or appear to be shorted. An open is not always due to the component itself, but may be due to a poor solder connection or a bent pin on the op-amp. Likewise, a short circuit may be due to a solder bridge. Of course, the op-amp itself can fail. Let’s examine the basic configurations, considering only the feedback and input resistor failure modes and associated symptoms.Faults in the Noninverting AmplifierThe first thing to do when you suspect a faulty circuit is to check for the proper power supply voltage. The positive and negative supply voltages should be measured on the op-amp’s pins with respect to a nearby circuit ground. If either voltage is missing or incorrect, trace the power connections back toward the supply before making other checks. Check that the ground path is not open, giving a misleading power supply reading. If you have verified the supply voltage and ground path, possible faults with the basic amplifier are as follows.Faults in the Voltage-FollowerThe voltage-follower is a special case of the noninverting amplifier. Except for a bad power supply, a bad op-amp, or an open or short at a connection, about the only thing that can happen in a voltage-follower circuit is an open feedback loop. This would have the same effect as an open feedback resistor as previously discussed.Common-mode Rejection RatioWanted signals appear on only one input or with opposite polarities on both input lines. These wanted signals are amplified and appear on the outputs as previously discussed. Unwanted signals (noise) appearing with the same polarity on both input lines are essentially cancelled by the diff-amp and do not appear on the outputs. The measure of an amplifier’s ability to reject common-mode signals is a parameter called the common-mode rejection ratio (CMRR).Ideally, a differential amplifier provides a very high for desired signals (single-ended or differential) and zero gain for common-mode signals. Practical diff-amps, however, do exhibit a very small common-mode gain (usually much less than 1), while providing a high differential voltage gain (usually several thousand). The higher the differential gain with respect to the common-mode gain, the better the performance of the diff-amp in terms of rejection of common-mode signals. This suggests that a good measure of the diff-amp’s performance in rejecting unwantedcommon-mode signals is the ratio of the differential gain Av(d) to the common-mode gain, Acm this ratio is the common-mode rejection ratio, CMRR.中文电子及电源技术的发展现代电源技术是应用电力电子半导体器件,综合自动控制、计算机(微处理器)技术和电磁技术的多学科边缘交叉技术。

Development of aSecure Electronic Marketplace for EuropeMichael WaidnerIBM Zurich Research LaboratoryCH 8803 Rüschlikon, Switzerlande-mail <wmi@>Abstract: Backed by the European Commission, a consortium of partners fromEuropean industry, financial institutions, and academia has embarked on a re-search project to develop the fundamentals of secure electronic commerce. Thegoal of Project SEMPER (Secure Electronic Marketplace for Europe) is to pro-vide the first open and comprehensive solutions for secure commerce over theInternet and other public information networks. We describe the objectives andsummarise the initial architecture of SEMPER.1IntroductionBacked by the European Commission, a consortium from European industry and aca-demia has embarked on a research project to develop the fundamentals of secure elec-tronic commerce. The goal of the 9-million ECU project, SEMPER (Secure Electronic Marketplace for Europe), is to provide the first open and comprehensive solutions for secure commerce over the Internet and other public information networks.A wide range of businesses are rapidly moving to explore the huge potential of net-worked information systems, especially with the Internet-based WWW (World-wide Web). The Internet, which already connects more than 3 million computers and a sub-stantially larger number of users, is growing at a breathtaking pace with thousands of newcomers every day. Although the Internet has its roots in academia and is still dominated by free-of-charge information, dramatic changes are expected in the near future. For instance, the WWW will be used for a wide variety of electronic commerce such as on-line trade or delivery of advanced multimedia information services. The evolution of broadband networks and “information highways” will intensify this trend. The need for secure transactions in this new business environment, which involves networks available to the general public, has triggered a number of related efforts. These initial developments are based almost exclusively in the US and most of them are limited to proprietary, or otherwise closed solutions, involving only electronic payment issues. In contrast, SEMPER is directed towards a comprehensive solution for secure electronic commerce, considering legal, commercial, social, and technical requirements as well as different options for an electronic marketplace.Proceedings of ESORICS 96, Rome, September 1996;LNCS 1146, Springer-Verlag, Heidelberg 1996, 1-14.SEMPER started on September 1st, 1995. The first of the three project phases ad-dresses a coherent security model and a generic, open security architecture for the electronic marketplace. This architecture is independent of specific hardware, soft-ware, or network architectures. The most fundamental electronic commerce services, such as secure offering, order, payment and information delivery, are also integrated in the first phase.Subsequent phases will concentrate on more advanced services. These will include fair exchange of documents, credentials, advanced document processing, notary serv-ices and multimedia-specific security services, such as protection of intellectual prop-erty rights. Multi-party security and protection of users’ privacy receive prime atten-tion. SEMPER uses and integrates existing architectures, tools, and services where appropriate.Trials will be provided for WWW and ATM-based broadband networks. They will demonstrate the broad applicability of SEMPER's architecture and services.The SEMPER project is part of the Advanced Communication Technologies and Services (ACTS) research program established by the European Commission Direc-torate General XIII for 1994-1998 [/acts/cec/].The members of the SEMPER consortium are Cryptomathic (DK), DigiCash (NL), EUROCOM EXPERTISE (GR), Europay International (B), FOGRA Forschungs-gesellschaft Druck (D), GMD - German National Research Center for Information Technology (D), IBM (CH, D, F), INTRACOM (GR), KPN Research (NL), Otto-Versand (D), r3 security engineering (CH), SEPT (F), Stichting Mathematisch Cen-trum / CWI (NL), University of Freiburg (D), University of Hildesheim (D). Banksys (B), Banque Générale du Luxembourg (L) and Telekurs (CH) are associated with SEMPER. IBM Zurich Research Laboratory provides the technical leadership for the project.2Electronic CommerceLike on a physical marketplace, the main purpose of an electronic marketplace is to bring potential sellers and buyers together:•Sellers offer their goods and buyers order these goods; together this is a two-party negotiation, sometimes ending with a contract.•Both seller and buyer might need certain certificates for such a contract. For in-stance, a buyer might only want to buy from sellers that are accredited with a well-known payment system provider, so that they can use a certain payment in-strument, or they may only trust them if a consumer organisation has declared them trustworthy, or a seller might be allowed to deliver certain goods only to residents of the European Union.•Sellers deliver their goods and buyers make payments; together this is a two-party (fair) exchange.— 2 —•Instead of goods, the buyer might receive a specific certificate that subsequently enables conditional access to certain services, e.g., like a subscription to a jour-nal.•Buyers or sellers might be dissatisfied with what has happened so far, i.e., several exception handlers and dispute handlers are necessary.•Some services require third parties to co-operate, e.g., notaries and financial in-stitutions.•Many services require that buyer and seller have some relations already estab-lished, e.g., to banks or government agencies. This requires registration and cer-tification, and in most cases also directory authorities.In all these actions, the parties have specific security requirements, namely integrity, confidentiality, and availability. Confidentiality includes anonymity which is often a requirement for browsing catalogues or purchases for small amounts.Several typical scenarios of electronic commerce are to be covered by SEMPER:•Mail-order Retailing: A retailer accepts electronic orders and payments, based on digital or conventional catalogues, and delivers physical goods.•On-line Purchase of Information: Like mail-order retailing, but with digital, maybe copyright-protected goods that are delivered on-line.•Electronic Mall: An organisation offers services for several service providers, ranging from directory services (“index”) over content hosting to billing services.•Subscriptions: An organisation offers services on a subscription basis, e.g., sub-scription to news services, database services, or journals. The subscription might be valid only for some time, and it might be transferable or not.•Statements: Transfer of electronic documents, supporting all kinds of security requirements, such as confidentiality and non-repudiation of delivery. A statement might be based on a pre-defined statement template certified by a third party.•Contract Signing: Two or more parties exchange signed copies of the same statement.•Insurance: Subscription to an insurance, payment of fees, regulation of damages.•Auctioning: Users participate in an auction, maybe anonymously, and with the usual fairness requirements.•Ticketing: A user buys a ticket that can be used to access a certain service for some time or exactly once, etc., and for that user or for the user’s family, etc.— 3 —Application NetworkApplication3Existing TechnologyThe development of electronic commerce on the Internet has come about in a very fast but highly disorganised manner. Currently, there is only a limited understanding of the functionality and security properties of services that are required by merchants and their potential customers. Coherent strategies for marketing, advertising, accounting, and payment are missing. Neither a comprehensive model of an electronic market-place nor a generic functional and security architecture exists.Most proposals for electronic commerce originated from one of the following three classes:Communication security protocols: Most proposals for secure electronic commerce are based on techniques for classical end-to-end security. The currently best known protocols are the following:•SHTTP [ReSc 95], PEM [Linn93], and MOSS [CFGM95] are extensions to HTTP, electronic mail, and MIME, respectively. In order to use them one has to modify the applications, e.g., one needs security enhanced browsers and servers in order to use SHTTP. They work on individual application layer messages, which is an advantage for electronic commerce because digital messages are used like paper documents: for disputes one needs individually signed messages. CommerceNet [] has developed some examples of how SHTTP can be used to simulate paper forms that must be filled-in and signed (e.g., cheques).•SSL [HiEl 95] and IPv6/IPsec [Atki95] offer secure communication below the ap-plication layer. Therefore they can be used almost transparently. Their main problem with respect to electronic commerce is that they do not work on docu-ments, i.e., the user does not receive something like a signature that can be stored and used in case of disputes.— 4 —All mentioned protocols use the same set of security mechanisms and cryptographic algorithms, primarily digital signatures based on RSA, encryption based on DES and RSA, and MD5 as hash function (for an explanation of all these techniques, see [Schn 96]). All of them were developed in the US, and since they provide an open interface to strong cryptography they are subject to US crypto export regulations. They all re-quire a public-key infrastructure. Both SSL and SHTTP are integrated in commercial products, and most vendors of web browsers and servers announced to support them in their products.Merchant servers with support for secure transactions: The best known example of such a commercial server comes from OpenMarket[http://www.openmarket. com]. From a security point of view, the heart of their architecture is a “payment switch”[GSPT 95]. The payment switch supports different types of customer identification (e.g., password, some secure tokens), collects payments (supporting different payment systems; OpenMarket announced to support CyberCash[http://www.cybercash. com]), and grants access to information (i.e., specific URL’s of short life time) after success-ful payment. The server supports SSL and SHTTP. Obviously the architecture is highly centralised and considers the server side only.Electronic on-line payment systems: Most of the existing work on electronic com-merce services concentrates on the development of electronic payment systems. The spectrum of systems includes (see [JaWa 96] for more details):•systems that do not use any strong protection methods and require prior registra-tion of user accounts, and may be considered as insufficiently secure;•systems that implement a credit card model, processing customer authentication and payment information by specific security protocols, e.g., iKP[BGHH 95]and the proposed Mastercard/VISA standard SET [SET 96]);•one system (ecash, from DigiCash, see also [Chau 89]) that implements an anonymous electronic cash model.Outside the Internet, some interesting, smartcard-based off-line payment systems were developed, which could be used on-line as well. The spectrum ranges from classical electronic wallets and purses to systems that provide strong multi-party security and anonymity (e.g., the system developed by the ESPRIT Project CAFE [BBCM 94]). The leading payment system companies, Europay/Mastercard/VISA intend to support transactions based on smartcards (they published joint specifications), and the US Financial Services Technology Consortium (FSTC) initiated a project that will use a PCMCIA card as “Electronic Checkbook,” also via Internet. All these approaches share the problem that the customer's stations need an interface to smartcards or PCMCIA cards, which is not the case in general, yet. Probably this will change in the near future.None of the different existing or proposed on-line payment systems are interoperable. Most of them do not provide strong multi-party security or user privacy.Public-key infrastructure: There are mechanisms and standards for key certification, e.g., CCITT X509. Up to now, there is no sufficient certification infrastructure for— 5 —public keys, but several projects aim at this. Examples are the TEDIS Project FAST, and activities within RARE and TERENA, based on the results of the EU VALUE Project PASSWORD. Several national post offices (e.g., the USPO) plan to provide such services.Miscellaneous:In addition there are several initiatives that primarily aim at co-ordination and consensus forming, like CommerceNet. Similar initiatives exist or are proposed in Japan and Europe.Beyond these systems, few other services are available for electronic commerce. The experimental NetBill [SiTy 95] system supports accounting and billing based on central billing servers. Several companies offer technology for secure metering or copyright protection based on superdistribution (or variant thereof) [MoKa 90]. Some companies offer tools for using EDI messages in electronic commerce over the Internet.What is missing? Some aspects of secure electronic commerce are not covered by any of the mentioned projects, or at least not in a sufficient form:•All listed technical projects deal with partial aspects of secure electronic com-merce only. No project aims at the complete picture, i.e., at defining a complete model and architecture for secure electronic commerce.•Although some systems are supposed to become standards, only few standardised API’s exist. Defining generic API’s and gateways between protocols is absolutely required for an open marketplace.•Most electronic commerce systems are closed: They use proprietary technology, or support only a specific set of protocols and mechanisms. Often they are based on one central server that acts as a trusted third party for all participants, per mar-ketplace. Often they require specific browsers and servers to be used.•Although most proposals use public-key cryptography, only little attention is paid to multi-party security. No decision procedures for disputes are defined, which would be necessary for non-repudiation of origin. Usually no security require-ments are explicitly formulated, and often no systematic security evaluation is per-formed.•The aspects of customer anonymity and privacy are not sufficiently considered yet. Neither are the requirements completely clear, nor are the technologies com-pletely available. Several payment systems, with ecash as the most advanced, provide some sort of anonymity, but anonymous payments without anonymous communication does not make much sense. No project deals with the more gen-eral problems like anonymous credentials.•Most systems assume a master-slave relation between seller’s server and buyer’s browser. The resulting asymmetry limits the complexity of protocols that can be performed in this model, and does not allow protocols between users (i.e., be-tween two slaves without master).•Most systems are limited to 2 parties. For instance, SSL supports a secure session between browser and server only. Integrating a secure connection to a third party like a “bank” in a payment system would be difficult.— 6 —•All projects that aim at prototype or product developments consider just on-line purchases, i.e., offer, order, payment and delivery. Multi-party problems (like auctioning) and fairness aspects (like contract signing, certified mail) are not con-sidered yet.•Most projects are US based. This means that their results are subject to US export control, i.e., they are not necessarily available outside the US. For instance, an SSL or SHTTP enabled browser developed in the US must not be exported unless the cryptographic algorithms are replaced by weak, i.e., breakable “export ver-sions.” Additionally, the law of some countries (e.g., France) does not allow to use products that support strong encryption of arbitrary data.4Objectives of SEMPERThe list of scenarios, actions, and security requirements in Section 2 already describe the working area of SEMPER. Within this area, the main objective of SEMPER is to develop, implement, trial and evaluate an open architecture for secure elec-tronic commerce, especially taking into account multi-party security and pri-vacy requirements.Open Architecture for Electronic Commerce:SEMPER defines an open and system independent architecture for electronic commerce:•The architecture is independent of specific hardware, operating systems, or net-works.•The architecture supports “plug-in” of new components, i.e., it is independent of specific service implementations, e.g., independent of the specific payment sys-tems used in the trials; most payment systems can be “plugged-in.”•The architecture is independent of specific business applications. It supports any business application of electronic commerce that can be expressed in our model,i.e., as sequence of exchanges.•The design process is open for public review. The SEMPER consortium has committed to publish all specifications, and appreciates security evaluations by third parties. The results of SEMPER will be used as input for standardisation. Security: As in the physical marketplace, all participants have specific security re-quirements:•Buyers often require to reliably authenticate the sellers they are dealing with.Note that it is easy to set up a WWW server and attach the name of a well known seller to it; even names that are already in use can be assigned; the highly fault-tolerant Internet tolerates such inconsistencies;•Buyers might wish to browse anonymously through the catalogues of sellers, and if money and goods are exchanged fairly, identification of the buyer is not neces-sary at all.— 7 —• A seller does not want to deliver on-line goods without some guarantee of pay-ment.•In some scenarios, a seller might require specific credentials from a buyer.•Buyer and seller might wish means for secure on-line payments, but certainly all parties — payer, payee and the financial services providers — do not want an in-creased risk compared to the physical marketplace.Multi-party security means that the security requirements of all parties are considered individually, and that all security requirements of a party are guaranteed without forcing this party to trust other parties unreasonably. In particular, mutual trust be-tween parties with conflicting interests like payer and payee in a payment is not as-sumed. Ideally, a party only has to trust itself and the jurisdiction and even the deci-sion of a court may be verified.In order to support the necessary degree of security, several cryptographic mecha-nisms must be applied. The architecture of SEMPER has to support•for authentication: certification; credentials; non-repudiation of origin, submis-sion, delivery; contract signing; fair exchange;•electronic payment systems following different payment models, e.g., pre-paid cash like, credit card like, cheque like, money transfers;•anonymous communication;•copyright protection.The Internet poses the strongest security challenges: It is completely open, without a central network security management, without any provisions for communication in-tegrity, authenticity, or confidentiality. Even worse, the structure and openness of Internet makes life for attackers as easy as possible. For instance, it is a trivial task to check the traffic routed through a node controlled by an attacker for telnet or ftp pass-words, or to send electronic mail under an arbitrary sender address via smtp. See, e.g., [ChBe 94] for a description of the most common security problems of the Internet. Thus, showing the feasibility of a secure and advanced electronic marketplace on the Internet proves feasibility for almost all other types of networks.Trials: The architecture and services developed by the SEMPER consortium will be evaluated by means of trials. The first trial will be based on the Internet only, while later trials will use ATM-broadband networks.The initial trials will be based on the minimum set of services that are necessary to secure the existing services of the 3 trial partners in SEMPER, namely •EUROCOM (Athens), offering on-line multi-media training courses;•FOGRA (Munich), offering several publications and on-line consulting;•Otto-Versand (Hamburg), offering a small part of their mail-order catalogue.— 8 —Transfer / Exchange of→for↓Money SigneddocumentInformationnothing (i.e., Transfer)Payment Certificatetransfer etc.InformationtransferMoney Fair moneyexchange Fair paymentwith receiptFair purchaseSigned documentSame as…Fair ContractSigningFair conditionalaccessInformation… in upper …… right half Fair information exchangeFig. 2. Transfers and exchanges of primitive types5Initial ArchitectureModel: The model of SEMPER describes business sessions in terms of sequences of transfers and exchanges similar to the dialogues of interactive EDI.A container is the general data structure for what can be transferred and exchanged. It contains several primitive types together with their security attributes in a tree-like structure, namely•signed documents, such as certificates, receipts, and signed statements;•information, such as digital goods, information necessary to access a service (e.g., an address and password or a cryptographic key that protects a video stream), and information necessary to access physical goods;•money.A container can be structured according to a template which also defines the seman-tics of its contents, and which might be certified by a third party (e.g., like today’s standard contracts for apartment rentals with fields to fill in). The concept of templates is similar to the concept of messages in EDI. Each template clearly defines the mean-ing of the data contained in the fields of the template.In a transfer,one party sends a container to one or more other parties. The sending party can define certain security requirements, such as confidentiality, anonymity, non-repudiation of origin. The sender receives an acknowledgement for each transfer, but this acknowledgement does not necessarily prove successful submission.A fair exchange is an exchange of containers where two or more parties have the as-surance that if they transfer something specific to the others, they will also receive something specific. Note that we require a guarantee of fairness. If no such guarantee is required, we can model such a conversation by several transfers.— 9 —quences as well, e.g., after "Contract" "Payment without Receipt" might also be enabled. The actual sequence of transfers and exchanges in a business session can either be determined directly by the users, or it can be described by a protocol for such business sessions. Of course, a protocol may branch, i.e., allow more than one sequence.Fig. 2 gives an overview of the possible exchanges of primitive types. Transfers are included as exchanges of “something” for “nothing.”Obviously, the matrix of Fig. 2 is complete with respect to pairs, but there may be different security requirements in detail. The initial architecture of SEMPER is two-party centred. The same considerations can be applied to the multi-party case. For instance, more than two parties might wish to sign a joint contract, or one sender might want to send a certified mail to several recipients.In the course of an ongoing business session, after each transfer or exchange, the par-ties are either•satisfied and thus willing to proceed with a certain number of other transfers or exchanges or•dissatisfied,in which case an exception or dispute handler is raised which might end up at a real court if all else fails.Layers of SEMPER: The main activity of SEMPER during its first 6 months was the definition of an initial model and architecture, and the specification of a basic set of services.The security architecture of SEMPER describes a layered structure in which the busi-ness applications are on the upper layer and services for secure commerce on the lower layers (see Fig. 4).— 10 —— 11 —Fig. 4. Architecture of SEMPER — Overview• The commerce layer offers high-level services for business sessions like “on-linepurchase of information” or “registration with service provider”, and template management.• The exchange layer supports fair exchange services.• The transfer layer provides the transfer services for sending information.• The supporting services are the usual cryptographic services, communication,archiving of data (keys, non-repudiation tokens, templates, audit), setting prefer-ences and handling access-control, a trusted user interface which the user can en-ter or be shown sensitive information (TINGUIN: Trusted INteractive Graphical User INterface).The architecture supports, but does not prescribe, the use of trusted hardware, like smartcards or electronic wallets. Commerce services, i.e., new scripts for business sessions, can be downloaded and added dynamically.SupportingServices TransferServicesCommerce LayerExchange LayerFig. 5. Initial design of SEMPERFig. 6. Integration of different service modules in SEMPER. A payment manager,for example, may manage different payment systems like SET/iKP and e-cash.The first actual design based on this architecture is summarised in Fig. 5. It supports transfer services and a fixed set of commerce services only. The functionality of the transfer layer is divided into the 3 fundamental blocks electronic payments, certifica-tion, and general statements which includes digital signatures.Each service block in Fig. 5 provides a generic interface and allows to integrate dif-ferent service modules that actually provide the service (see Fig. 6). For instance, the payment service block provides a generic “external” payment API that is independent of specific payment systems [APAW 96]. A concrete payment system can be integrated by providing an “adapter” mapping the concrete system’s API to an “internal” API of the payment service block. Currently one internal API for account based systems (like SET or iKP) and one for cash-like payment systems (like ecash) are being designed. The basic trials will use IBM’s iKP and DigiCash’s ecash for electronic payments, GMD’s SecuDE toolkit for X.509 certificates, and crypto toolkits developed by Cryptomathic and GMD for statements. The system will be implemented in software only. Later versions might use SET instead of iKP (both implementing the same pay-ment model).Trust in Components: Naturally, without correctly working components, no security can be achieved:•Software components may not behave as specified and, e.g., sign fake statements.•The user-interface may display wrong amounts to pay, or questions to decide, so called masquerade attacks.— 12 —•Confidential user-input, such as credit-card numbers or PINs, may be stored and distributed over the network.•Secret keys may be retrieved and misused.Therefore, a user of SEMPER has to believe that their components and user-interface behave correctly and protect their security. We call this trust in components. Since SEMPER provides an open architecture, we cannot assume that all parties trust every component. However, trust of the parties involved can be increased by several meas-ures:•public design, implementation, and evaluation.•an open architecture which allows to choose between different manufacturers;•dedicated security modules.In addition, each user will be able to decide whom and what to trust. If some compo-nents, such as specific payment systems, are not trusted, these components will be moderated by trusted components. For trusted user-interaction, SEMPER provides a local “Trusted Interactive Graphical User Interface” (TINGUIN; see Fig. 5) which is unambiguously distinguishable from the user-interface of the business application, and should be ideally implemented on a separate security module, e.g., a secure electronic wallet.6SummarySEMPER is the first open architecture for multi-party secure electronic commerce.
