We explore the influence of cooperative jamming on covert communication for integrated
satellite–terrestrial relay networks (ISTRN) in this article, where one full-duplex relay is …

This paper considers covert communications in non-orthogonal multiple access (NOMA)-
based vehicular networks. In the vehicular networks, the source vehicle aims to hide two …

In this paper, we investigate the secure content delivery issue for device-to-device networks
based on the trust evaluation mechanism and covert communication model. Specifically, in …

Wireless connectivity in smart cities relies on widely deployed Internet of Things (IoT)
systems. However, the broadcast and open nature of wireless channels in such systems …

This work proposes a covert communication scheme in a cognitive radio network where a
secondary transmitter (ST) transmits confidential information to a secondary receiver under …

Despite its potential for reducing the detection probability at the warden, the effectiveness of
covert communication in practical situations is often hindered by harsh wireless signal …

We consider a covert communication scenario, where a legitimate transmitter (Alice) applies
non-orthogonal multiple access (NOMA) to communicate with a covert user (Bob) and a …

The broadcast nature of wireless communication systems makes wireless transmission
extremely susceptible to eavesdropping and even malicious interference. Physical layer …

We aim to develop a system-level security solution for a large-scale device-to-device (D2D)
network against adversaries based on covert communication. The D2D network underlays a …

Covert communications can hide the existence of a transmission from the transmitter to
receiver. This paper considers an intelligent reflecting surface (IRS) assisted unmanned …
