Exploring Secrecy Outage Probability of AF-NOMA and AF-OMA Networks
Journal of Communications, 2019—A new design of non-orthogonal multiple access (NOMA) is explored in this study under secrecy outage probability performance considerations. In particular, the Amplify-and-Forward (AF) relaying scheme is applied in this system model.

Secrecy Outage Analysis for Downlink Transmissions in the Presence of Randomly Located Eavesdroppers
IEEE Transactions on Information Forensics and Security, 2017 International audienceWe analyze the secrecy outage probability in the downlink for wireless networks with spatially (Poisson) distributed eavesdroppers (EDs) under the assumption that the base station employs transmit antenna selection (TAS) to enhance ...

In this paper, we study a multiuser uplink network consisting of one base station (BS), multiple users and one eavesdropper (E), where the users are intended to transmit their confidential messages to BS, while the eavesdropper attempts to tap their ...

Secrecy outage probability for the multiuser downlink with several curious users
2016 IEEE Wireless Communications and Networking Conference, 2016This paper studies the physical layer security in a multi-user downlink, where a single user is selected for secret transmission during each time frame. Current works usually assume a worst case where all unselected users are curious and act as eavesdroppers, and conclude that no multiuser diversity is achievable for secrecy when the number of users is

Secrecy outage probability in cognitive radio networks subject to Rayleigh fading channels
International Conference on Advanced Communication Technologies and Networking, 2018Wireless communication systems are vulnerable to eavesdropping attack in which the attacker overhear the transmitted data in the network. Hence, the physical-layer security is of utmost importance to protect the wireless communications against the ...

Secrecy Outage Performance Analysis of Dual-Hop RF-UOWC Systems
IEEE Systems Journal, 2023This article investigates the secrecy performance of a dual-hop radio frequency-underwater optical wireless communication (RF-UOWC) system. Using stochastic geometry theory, the eavesdroppers are modeled as a Poisson point process distribution, and RF ...
