Secure Communication with a Wireless-Powered Friendly Jammer [PDF]
, 2014 In this paper, we propose to use a wireless-powered friendly jammer to enable secure communication between a source node and destination node, in the presence of an eavesdropper. We consider a two-phase communication protocol with fixed-rate transmission.

Security in Cognitive Radio Networks
, 2014 In this paper, we investigate the information-theoretic security by modeling a cognitive radio wiretap channel under quality-of-service (QoS) constraints and interference power limitations inflicted on primary users (PUs).

Enhancing wireless security via optimal cooperative jamming [PDF]
, 2012 In this work, we analyze the secrecy rate in a cooperative network, where a source node is assisted by relay nodes via cooperative jamming for delivering a secret message to the destination in the presence of an eavesdropper node.
