Security-Aware Relaying Scheme for Cooperative Networks With Untrusted Relay Nodes - 2015
This paper studies the matter of secure transmission in dual-hop cooperative networks with untrusted relays, where each relay acts as both a possible helper and an eavesdropper. A security-aware relaying theme is proposed, that employs the alternate jamming and secrecy-enhanced relay choice to prevent the confidential message from being eavesdropped by the untrusted relays. To evaluate the performance of the proposed methods, we have a tendency to derive the lower sure of the achievable ergodic secrecy rate (ESR), and conduct the asymptotic analysis to look at how the ESR scales as the amount of relays will increase.
