In this paper, we investigate the secrecy outage performance of the decode-and-forward cognitive relay network with the existence of the co-channel interference, where all nodes are equipped with single antenna and all channels experience Rayleigh fading channels, which are also independent non-identical distribution (i.n.i.d). We also consider the multiple user selection scheme and the single eavesdropper, which could wiretap the information at each hop. There is no evidence of the direct links from the source to the destinations because of the bad conditions. To evaluate the system secrecy performance, we derive the closed form expressions of the secrecy outage probabilities, and the Monte Carlo simulations are also presented to validate the accuracy of the theoretical analysis.
