Abstract:
Physical layer authentication allows users to be authenticated only on the basis of the peculiar characteristics of their transmission channels. With the aim of improving physical layer authentication accuracy, we consider cooperative communications exploiting a set of relay nodes located between the supplicant and the authenticator. These relay nodes can behave in different ways, passively or actively cooperating to establish whether or not to forward messages to the final recipient. The presence of cooperating nodes provides the authenticator with a large number of features, which can be exploited and combined to identify the original source of packets using both statistical and machine learning-based techniques. We also consider two basic power allocation strategies, and provide performance assessments based on both theoretical arguments and numerical simulations.
