Cognitive Radio (CR) is a prominent technology in a world of wireless communication that promises to alleviate the spectrum shortage problem and improves the efficiency of spectrum utilization. Cognitive Radio Networks (CRNs) deal with opportunistic spectrum access to utilize the limited radio spectrum in its full scale. Since, CRN is dynamic in nature any node can join or leave the network at any time. These flexible characteristics mean that the issue of secure communication in CRNs becomes more critical than for other conventional wireless networks.
