Abstract

Because of the openness of the wireless relay channel, the confidential information transmitted in the channel is very easy to be eavesdropped on by malicious eavesdroppers and cause information leakage. In specifically, a friendly jammer will transmit a jamming signal to confound an eavesdropper attempting to listen in on a relay transmission. For wireless relay networks using the Rayleigh fading channel model, this research proposes a physical layer security technique based on cooperative interference. In the system, we design two-time stages to realize the transmission of the source to the user. During the initial phase, the signal source transmits a composite signal to both the user and the relay. In the second phase, the confidential information is relayed and artificial noise is generated by friendly jammers to confuse eavesdroppers. Through our proposed method, we derive precise analytical expressions for the intercept probability (IP) and outage probability (OP). The correctness of the theoretical derivation is verified by numerical results and theoretical simulation.
