The bit error rate of data signal (data BER) of a key-based physical layer authentication (PLA) scheme suffers from a non-negligible performance loss, mainly caused by the authentication tags taking power from data symbols and interfering with the data demodulation. Considering the orthogonality among different orbital angular momentum (OAM) modes, in this paper, an OAM-assisted PLA (OAM-PLA) scheme is proposed to improve the performance of data BER. The data BER of the proposed OAM-PLA scheme over the Rician fading channel has better performance than the conventional PLA scheme.
