This paper investigates the leakage rate based hybrid untrustworthy relay selection strategy. The investigation considers a dual-hop multiple half/full-duplex untrustworthy bi-directional amplify-and-forward wireless relaying network in the system model. The investigation also considers that the untrustworthy relay terminals are under the effect of a finite number of friendly jammers' interference. According to analytical, asymptotic and Monte Carlo simulation results, the hybrid untrustworthy relay selection strategy achieves cooperative diversity order in high signal-to-noise regimes. However, friendly jammers and loop interference severely affect the system performance and degrade the achievable cooperative diversity order from M to 0 and also cause system coding gain losses.
