Physical layer security (PLS) has been extensively explored as an alternative to
conventional cryptographic schemes for securing wireless links. Many studies have shown …

Non-orthogonal multiple access (NOMA) scheme is emerging as a favourable multiple
access scheme for future 5G networks. Compared to orthogonal multiple access techniques …

In this work, we study the secrecy performance of a reconfigurable intelligent surfaces (RIS)-
aided wireless communication system in the presence of an eavesdropping user …

Non-orthogonal multiple access (NOMA) has been widely recognized as a promising way to
scale up the number of users, enhance the spectral efficiency, and improve the user-fairness …

This paper investigates physical layer security (PLS) in cognitive radio inspired non-
orthogonal multiple access (CR-NOMA) networks with multiple primary and secondary …

In this work, we investigate a novel covert communication system, where the legitimate
transmitter attempts to communicate with a covert user in the presence of a warden and the …

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

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 …

Integrated satellite terrestrial networks and non-orthogonal multiple access (NOMA) have
been confirmed to be promising and effective approaches to achieve substantial …

With increase in the use of social networks, we also need the increase in the security of
those networks. Making the connection secure is critical and the priority now a day so that …
