Continuous Physical Layer Authentication Using a Novel Adaptive OFDM System

Traditional authentication techniques for wireless communications are facing great challenges, due to the open radio propagation environment and limited options of transmission techniques. A new continuous physical layer authentication technique with time-varying transmission parameters is investigated to enhance the security of Orthogonal Frequency Division Multiplexing (OFDM) system. A Precoded Cyclic Prefix (PCP) sequence, which introduces an additional signaling link to carry the time-varying transmission parameters, is employed in each OFDM symbol for physical layer authentication.
