802.11-2016 中定义的基于飞行时间的测距机制提供了一系列过于丰富的参数,无法在供应商之间以类似的模式实现,除非针对合理的参数集制定进一步的指导。我们研究了 802.11-2016 FTM,并表明简单的 FTM 帧观察可以轻松识别单个芯片组。我们还表明,学习机可以识别执行 FTM 交换的各个机器,即使这些机器实现相同的芯片组或相同的硬件平台。我们还提出了基于 FTM 交换观察来缓解单个设备模式的方法。
The time-of-flight based ranging mechanism defined in 802.11-2016 offers a range of parameters too rich to be implemented with similar pattern among vendors, unless further guidance is formulated on what parameter sets are reasonable. We examine 802.11-2016 FTM, and show that simple FTM frame observation can easily allow for individual chipset identification. We also show that a learning machine can recognize individual machines performing FTM exchanges, even when these machines implement the same chipset or the same hardware platform. We also suggest ways to mitigate individual device patterning based on FTM exchange observation.
