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

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 …

In this paper, we investigate the secrecy outage performance of a typical cooperative
downlink non-orthogonal multiple access (NOMA) system over Nakagami-m fading channel …

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 …

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 …

In this work, the secrecy of a typical wireless cooperative dual‐hop non‐orthogonal multiple
access (NOMA)‐enabled decode‐and‐forward (DF) relay network is investigated with the …

To enhance the secrecy of wireless transmission, we propose a cooperative user relaying
NOMA scheme, in which the near user works in full-duplex mode by transmitting jamming …

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

The secrecy outage probability (SOP) performance is investigated for a cooperative non-
orthogonal multiple access system under eavesdropping attack, where a base station …

This letter investigates a jammer-aided cooperative non-orthogonal multiple access (NOMA)
system, where one relay is used to deliver information and other relays are acted as …
