7月23日下午2:30-4:00,美国韦恩州立大学(Wayne State University, USA)Fengwei Zhang博士应邀在广州大学行政西楼前作428会议室给计算机学院师生做了题为“Nailgun: Break the privilege isolation on ARM”的学术报告,会议由计算机学院副院长王国军教授主持。
报告中Fengwei Zhang博士首先介绍了处理器的调试模式,包括传统的物理访问调试模式和在ARMv7之后出现的处理器间调试模式,后者可以控制芯片中的一枚处理器,使其能够暂停并调试另一目标处理器。接着,Fengwei Zhang博士提出了该模式存在的安全问题——在调试模式下使用Nailgun工具控制另一拥有更高特权处理器可以获取设备的资源。最后,Fengwei Zhang博士与王国军教授及参会的师生就Intel处理器是否存在相同问题、关闭调试模式以外的解决方案等问题展开了讨论。此次报告让在场的师生获益良多。
