Secure Transmission Design for Cognitive Radio Networks With Poisson Distributed Eavesdroppers

Xu, Xiaoming; He, Biao; Yang, Weiwei; Cai, Yueming; Zhou, Xiangyun

Description

In this paper, we study physical layer security in an underlay cognitive radio (CR) network. We consider the problem of secure communication between a secondary transmitter-receiver pair in the presence of randomly distributed eavesdroppers under an interference constraint set by the primary user. For different channel knowledge assumptions at the transmitter, we design four transmission protocols to achieve the secure transmission in the CR network. We give a comprehensive performance...[Show more]
