Abstract :This paper investigates the physical layer security of orthogonal frequency division multiplexing technique. The investigation considers a multi -user untrustworthy half/full-duplex based two-way wireless relay with a finite number of friendly jammers in the system model. According to Monte-Carlo simulation results, the system model that operates in full-duplex mode achieves slightly better secrecy outage performance than the system model that operates in half-duplex mode. The results also show that friendly jammers , besides minimizing the information leakage, degrade the system performance severely and cause system coding gain losses in high signal-to-noise ratios.
