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 …

A new paradigm of uplink non-orthogonal multiple access along with multiple
eavesdroppers to achieve secrecy transmission is studied in this paper. We investigate the …

We study the secrecy transmission of uplink non-orthogonal multiple access (NOMA) with
single antenna and multi-antenna users in presence of an eavesdropper. Two phases are …

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 secure transmission for non-orthogonal multiple access (NOMA)
systems where the imperfect successive interference cancellation (SIC) is considered at …

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 …

In this article, we study the physical-layer security (PHY-security) improvement method for a
downlink nonorthogonal multiple access (NOMA) system in the presence of an active …

To accommodate the stringent requirements of enhanced coverage quality and improved
spectral efficiency, simultaneous transmitting and reflecting reconfigurable intelligent surface …

The application of successive interference cancellation (SIC) introduces critical security risks
to cooperative non-orthogonal multiple access (NOMA) systems in the presence of …

In this paper, we consider the physical layer security of a downlink non-orthogonal multiple
access (NOMA) system, in which users' quality of service (QoS) requirements are …
