Novel Noise Injection Scheme to Guarantee Zero Secrecy Outage under Imperfect CSI [PDF]
Entropy, 2023 The paper proposes a novel artificial noise (AN) injection strategy in multiple-input single-output multiple-antenna-eavesdropper (MISOME) systems under imperfect channel estimation at the legitimate channel to achieve zero secrecy outage probability ...

Secrecy outage probability of cooperative network through distributed Alamouti code
2015 IEEE 26th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2015 Abstract--- The cooperative diversity technique combined with distributed space-time coding can efficiently improve the secrecy capacity and transmission reliability of wireless communication systems. In this paper, a multicast cooperative relaying system based on distributed Alamouti space-time coding was considered, in order to jam an eavesdropper ...

Secrecy outage probability based access strategy for device-to-device communication underlaying cellular networks [PDF]
Tongxin xuebao, 2016 A secure access strategy for D2D (device-to-device) communications underlaying cellular networks based on the secrecy outage probability was proposed.Firstly,the secrecy outage probability in the worst case was derived and a transmission power ...

Transactions on Emerging Telecommunications Technologies, 2015 AbstractIn this paper, we study the multiple‐input multiple‐output multiple‐eavesdropper wiretap channel in the nonergodic and ergodic scenarios, both with stationary Rayleigh distributed fading channels. For the ergodic scenario, we derive a new closed‐form expression for the ergodic secrecy capacity with full channel state information at the ...

Secrecy outage probability of cognitive decode-and-forward relay networks
2016 IEEE International Conference on Communications Workshops (ICC), 2016 This paper investigates the secrecy performance of cognitive decode-and-forward (DF) relay networks with multiple primary users (PUs) receivers, one secondary user (SU) source, multiple SU relays, one SU destination and one SU eaves-dropper over Nakagami-m fading channels.

Secrecy outage probability of relay networking in multiple destination and eavesdropper scenarios
2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014 This paper investigates the secrecy outage probability of multicast cooperative relay networking in the presence of multi-destination and multi-eavesdropper nodes. The study is carried out in a multicast relay communication scenario whereby multi-eavesdropper nodes attempt to overhear the source message.
