This study investigates the co‐channel interference effects on the leakage rate based untrustworthy relay selection strategies. The investigation considers half‐duplex, full‐duplex, and hybrid leakage rate‐based untrustworthy relay selection strategies. The hybrid‐based selection strategy dynamically switches between half‐duplex and full‐duplex modes. The investigation also considers a dual‐hop untrustworthy amplify‐and‐forward based half/full‐duplex bi‐directional wireless relaying network in the system model. In addition, a finite number of friendly jammers and co‐channel interference affect to the untrustworthy relay terminals. According to analytical, asymptotic, and Monte‐Carlo simulation results, the co‐channel interference slightly degrades the outage probability performance curves and causes system coding gain losses in high signal‐to‐noise ratio regimes. Results also show that the co‐channel interference degrades the system achievable rate performance and causes additional system coding gain losses in high SNR regimes. Results also show that co‐channel interference does not have any effect on the system security trade‐off performance.
