云南大学软件学院实验报告 课程：无线网络安全实验学期：2017-2018学年春季学期任课教师：张云春 专业：信息安全学号：________ 姓名： _______ 成绩：___________ 实验6蓝牙技术破解 一、实验目的 1.使用手机和相关蓝牙设备，开启蓝牙，对蓝牙技术进行深入学习，并模拟蓝牙技术的攻击。 2.使用专业工具对蓝牙PIN （个人身份码）进行破解。 二、实验内容 1.简要分析蓝牙设备的两种认证方式“传统配对”和“安全简化配对”方式。并对实验所选设备 的认证模式进行确认。 传统配对：该种配对方式建立在两台设备的BD_ADDR，由发起者创建的16字节随机数，用户 在两台设备上手动输入的PIN码（用户无法更改PIN码的固定PIN码”除外）。 安全简化配对：这种配对方式与传统配对方式最大的区别在于不需要手动输入pin码，在设备寻找到对方设备之后，双方计算后自动生成6位随机数，双方互相确认对方生成的随机数与自己 的是否相同，如果相同，则确认了建立通信的对方的身份，完成配对。 为了后面步骤中截获pin码，这里实验设备选择了一台具有传统配对方式的塞班手机，并且因为没有硬件支持，笔记本电脑没有办法抓到蓝牙的数据包，所以选用了一台方便导出蓝牙日志文 件的安卓手机。在下图中，打开了开发者选项中的HCI信息收集日志。 ■an钿电胃 賢特睦Bl钛誉
