In this letter, we investigate the secrecy outage performance of a cooperative non-
orthogonal multiple access (NOMA) network, where a base station (BS) communicates with …

The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users in the
same frequency band to improve the spectral efficiency. Whereas a security flaw emerges in …

This paper studies the impacts of antenna selection algorithms in decode‐and‐forward (DF)
cooperative nonorthogonal multiple access (NOMA) networks, where the secure information …

The objective of this paper is to propose techniques for enhancing the physical layer security
(PLS) performance of half-duplex cooperative non-orthogonal multiple access (HD-CNOMA) …

We investigate the problem of secure non-orthogonal multiple access (NOMA) against full-
duplex proactive eavesdropping, where the eavesdropper performs passive eavesdropping …

This paper considers the secrecy outage performance of a multiple-relay assisted non-
orthogonal multiple access (NOMA) network over Rayleigh fading channels. Two slots are …

We propose a novel non-orthogonal multiple access (NOMA)-inspired jamming and relaying
scheme to enhance the physical layer security of untrusted relay networks. Particularly …

This correspondence studies a new secrecy beamforming (SBF) scheme for multiple-input
single-output non-orthogonal multiple access (MISO-NOMA) systems. In particular, the …

A novel secrecy scenario of uplink non-orthogonal multiple access (NOMA) along with
cooperative jammer (s) to improve secrecy performance is studied in this work. We first …

In this paper, we develop a non-orthogonal multiple access (NOMA)-based two-way relay
network with secrecy considerations, in which two users wish to exchange their NOMA …
