By considering security constraints, we have derived exact expressions for the average secrecy rate and the secrecy outage probability. Moreover, analytical expressions of the false secrecy probability are derived for the suboptimal relay selection based on statistical CSI-E, which are used as the constrained functions of new selection metrics. Furthermore, our work achieves a better tradeoff between the outage probability and the false secrecy probability. The accuracy of our performance analysis is verified by simulation results.
