Secure Physical Layer Slope Authentication Method in Wireless Communications and Apparatus

摘要

A wireless communication method and device include: a transmitting device dividing a to-be-transmitted signal into a plurality of packets by using a pre-agreed key; acquiring a preset equivocation threshold; according to the equivocation threshold, determining a power parameter adjustment factor for each of the packets; for each of the packets, performing power adjustment on a signal of the packet according to a power parameter adjustment factor of the packet; and transmitting the to-be-transmitted signal after power adjustment. After receiving the signal, the receiving device groups the signals according to the pre-agreed key, and calculates the power of each packet; determines a test statistic according to the power of each packet, and determines the test statistic whether the quantity is greater than or equal to a preset statistic threshold. If so, it determines that the signal is a tag signal, and if not, that it is a regular signal.
