This paper investigates secure cooperative communications in untrusted relay networks,
where a source coordinately communicates with multiple near users and a far user, and the …

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 letter investigates secure transmission for a cooperative non-orthogonal multiple
access (NOMA) network consisting of multiple near users (NUs), a far user (FU) and an …

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 analyzes the secrecy capacity of a cooperative relaying system using non-
orthogonal multiple access (NOMA). A new cooperative NOMA scheme is proposed, where …

In this paper, we develop a non-orthogonal multiple access (NOMA)-based cooperative
network against multiple eavesdroppers, in which the source delivers confidential …

In this paper, we investigate cooperative secure transmission in non-orthogonal multiple
access (NOMA) networks where a source (Alice) intends to transmit confidential messages …

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

This paper proposes a new scheme to enhance the secrecy performance of non-orthogonal
multiple access (NOMA)-based coordinated direct relay transmission (CDRT) systems with …

In this paper, we consider the physical layer security of a downlink cooperative multiple-
input single-output (MISO) non-orthogonal multiple access (NOMA) network over Nakagami …
