Abstract
A method of security detection for a physical layer authentication system takes into account the signal-discriminating ability of an active adversary. The distance to the active adversary is estimated by an authorized transmitter based on its broadcast signal and, based on the distance estimate, the signal-to-noise ratio (SNR) of the adversary is also estimated.
