ABSTRACT = {Wireless communications have to face to several different security issues in 
practice due to the nature of broadcast. The information theory is well known to provide 
efficient approaches to address security issues in wireless communications, which attracts 
much attention in both industry and academia in recent years. In this paper, inspired by 
information theory, we study the outage probability of the opportunistic relay selection 
based on cognitive decode-and-forward relaying with the secrecy consideration. 
Specifically, the closed-form expression of the outage probability is proposed. Moreover, 
the asymptotic performance evaluation on the basis of the analytical results is 
investigated. The simulation results show that the relay selection can reduce the outage 
probability in accordance with our theoretical analysis.},
