On the Secure Outage Performance for Dual-Hop Network Coding Systems with Cooperative Jamming
Hequn Liu · International Journal of Information and Electronics Engineering · 2014
In this paper, a design of cooperative network coding (NC) and jammer relay (JR) is proposed for this two-way network in order to improve the security of the date exchange. Considering the system over Rayleigh fading channels in the presence of one eavesdropper and two relays, we study secrecy outage (including the probability of non-zero secrecy capacity and secure outage probability), respectively. In this paper, one relay is regarded as NC relay which is used to make codes by xor in order to prevent eavesdropper's interception while the other one is regarded as a jammer relay which can send interference to eavesdropper. We derive exact expressions for the secure outage probability. The accuracy of our performance analysis is verified by simulation results.
