Abstract
Provided is a physical layer blind authentication method for a time-varying fading channel based on belief propagation. The method includes that: a transmitter transmits a carrier signal to a wireless channel, the carrier signal includes an authentication signal, a pilot signal and an information signal, and the wireless channel is the time-varying fading channel; a receiver receives the carrier signal, and performs BKIC processing and differential signal processing on the carrier signal to obtain a target authentication signal, the receiver obtains a reference signal based on a key and the pilot signal, performs the differential signal processing on the reference signal to obtain a reference authentication signal, and calculates a correlation between the target authentication signal and the reference authentication signal to obtain a test statistic; and compares the test statistic with a prescribed threshold to determine whether the carrier signal is capable of passing authentication.
