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

Owing to the eminent performance gain, non-orthogonal multiple access (NOMA) has been
regarded as a promising approach to achieve high throughput and low latency for the next …

This paper investigates the secrecy outage performance for a large-scale downlink system
with full-duplex (FD) non-orthogonal multiple access (NOMA) transmission aided by artificial …

The key idea of non-orthogonal multiple access (NOMA) is to serve multiple users in the
same resource block to improve the spectral efficiency. Whereas due to the resource …

We investigate physical layer security of an uplink NOMA system consisting of one base
station, multiple users and one eavesdropper. During each uplink transmission, two users …

This paper investigates the secure transmission in a simultaneously transmitting and
reflecting reconfigurable intelligent surface (STAR-RIS) assisted uplink non-orthogonal …

We investigate a secrecy-enhancing design for cooperative downlink and uplink non-
orthogonal multiple access (NOMA) transmissions with an untrusted relay. A source uses the …

This paper investigates the impact of physical layer secrecy on the performance of a unified
non-orthogonal multiple access (NOMA) framework, where both external and internal …

This paper considers a secure nonorthogonal multiple access system, where confidential
messages are transmitted from a base station to multiple legitimate destinations and …

In this paper, we propose a novel beamforming design to enhance physical layer security of
a non-orthogonal multiple access (NOMA) system with the aid of artificial noise (AN). The …
