Abstract:

This paper studies the physical layer authentication problem in a multi-hop network assisted by a full-duplex relay. Since the self-interference channel is a unique physical layer feature of the full-duplex device, we incorporate the characteristics of self-interference channel into the authentication process for the first time. By judging the estimators of channels and the statistical properties of the received signal, two kinds of authentication methods are proposed. Then we turn the authentication problem into a simple hypothesis test problem. Two one-bit quantizers are used to develop the test statistic in our two-dimensions authentication scheme. False alarm rate and probability of detection are defined for performance analysis. After Monte Carlo simulations, numeral results show that our proposed two-dimensional authentication scheme can achieve a high probability of detection along with a low false alarm rate whether the spoofing behavior occurs at the source or the relay.
