In this paper, we investigate the physical layer security of multiple-input single-output single-antenna eavesdropper relaying networks with imperfect channel state information. Different from traditional strategies in relay systems, which would halt the communication if the relay could not decode the signal successfully, we propose a robust secure transmission strategy which switches between cooperative...
We investigate physical-layer security (PLS) for multi-antenna and multi-relay networks with transmit beamforming and relay selection under feedback delay. The connection outage probability (COP) and secrecy outage probability (SOP) are derived to evaluate the reliability and security. Besides, we introduce a novel definition of the reliable-and-secure probability (RSP) to combat the correlation between...
