无线物理层操作是最近发现的用于选择性分组混淆的技术。这个过程利用了收发器设计的独特性和专有性，而不是制造缺陷。到目前为止，前同步码操作仅在2.4 GHz频段的低数据速率收发器上成功演示。这封信首次调查了常见的5 GHz IEEE 802.11a和IEEE 802.11ac无线收发器上的前导码操作的有效性。在本文中，证明了可以操纵前导短训练序列长度以使用少于20个分组以大于99%的准确度在测试中的六个收发器设计之间进行辨别。
Wireless physical layer manipulation is a recently discovered technique for selective packet obfuscation. This process exploits the unique and proprietary nature of transceiver designs rather than manufacturing imperfections. To date, preamble manipulation has only successfully been demonstrated on low data rate transceivers operating in the 2.4 GHz band. This Letter investigates the effectiveness of preamble manipulation on common 5 GHz IEEE 802.11a and IEEE 802.11ac wireless transceivers for the first time. Herein it is demonstrated that the preamble short training sequence length can be manipulated to discern among the six transceiver designs under test with greater than 99% accuracy using fewer than 20 packets.
