Covert Communication Achieved by a Greedy Relay in Wireless Networks

Hu, Jinsong; Yan, Shihao; Shu, Feng; Li, Jun; Wang, Jiangzhou; Zhou, Xiangyun


Covert wireless communication aims to hide the very existence of wireless transmissions in order to guarantee a strong security in wireless networks. In this work, we examine the possibility and achievable performance of covert communication in amplify-and-forward one-way relay networks. Specifically, the relay is greedy and opportunistically transmits its own information to the destination covertly on top of forwarding the source’s message, while the source tries to detect this covert...[Show more]
