Secrecy outage of threshold-based cooperative relay network with and without direct links

open access: yesEURASIP Journal on Information Security, 2018
In this paper, we investigate the secrecy outage performance of a dual-hop decode-and-forward (DF) threshold-based cooperative relay network, both with and without the direct links between source-eavesdropper and source-destination. Without assuming that

Secrecy outage probability analysis for RIS‐assisted NOMA systems [PDF]

open access: yesElectronics Letters, 2020
In this Letter, the physical layer security for a novel reconfigurable intelligent surface (RIS)‐assisted non‐orthogonal multiple access (NOMA) system in a multi‐user scenario is investigated, where the authors consider the worst case that the eavesdropper also utilises the advantage of the RISs.

On secrecy outage probability for downlink NOMA systems with relay–antenna selection [PDF]

open access: yesEURASIP Journal on Advances in Signal Processing, 2021
AbstractSecure transmission is essential for future non-orthogonal multiple access (NOMA) system. This paper investigates relay–antenna selection to enhance physical-layer security of cooperative NOMA system in the presence of an eavesdropper, where multiple antennas are deployed at the relays, the users, and the eavesdropper.

Outage Probability and Secrecy Capacity of a Non-orthogonal Multiple Access System

open access: yes2017 11th International Conference on Signal Processing and Communication Systems (ICSPCS), 2017
In this paper, we analyze the outage probability and secrecy capacity of a non-orthogonal multiple access (NOMA) system in the presence of an eavesdropper. In order to enhance spectral efficiency, a base station communicates with two users simultaneously

Probability of Secrecy Outage in Cognitive Radio Networks over Rician-Fading Channels [PDF]

open access: yes, 2016
In Rician-fading scenario, cognitive radio networks (CRNs) with a source (S) in a secondary system transmitting its confidential information to a legitimate destination (D) in the presence of an eavesdropper, are considered in this paper. Under CRNs, the
