Secure Communication in Millimeter Wave Relaying Networks
IEEE Access, 2019 The use of relay can expand the coverage of millimeter-wave (mmWave) signals, whereas it may increase the risk of information leakage due to the additional link from source to relay.

Outage probability of selective decode and forward relaying with secrecy constraints
CoRR, 2011 We study the outage probability of opportunistic relay selection in decode-and-forward relaying with secrecy constraints. We derive the closed-form expression for the outage probability. Based on the analytical result, the asymptotic performance is then investigated. The accuracy of our performance analysis is verified by the simulation results.

On the Optimum Secrecy Outage Probability and Ergodic Secrecy Rate over Wireless Channels
We study the secrecy of wireless channels in the presence of an eavesdropper, where the channels are random and the transmitter only has knowledge of the channel statistics. We investigate the optimal input distribution with respect to several secrecy metrics: the Secrecy Outage Probability (SOP), defined as the probability that the coding rate $r ...
