In this paper, we propose a novel secure buffer-aided relay selection that is capable of operating both virtual full-duplex (VFD) and half-duplex (HD) transmissions in a hybrid manner. The proposed scheme consists of five modes: two unicast modes, a broadcast mode, cooperative beamforming, and a VFD mode. Since the VFD mode has the potential of achieving a higher secrecy capacity than the other four HD modes, the proposed relay selection algorithm gives the highest priority to activating the VFD mode. Our performance results demonstrate that the proposed secure relay selection scheme outperforms the benchmarks in terms of the secrecy outage probability.
