Information security has always been a critical issue in wireless networks. Apart from other
secure techniques, covert communication emerges as a potential solution to security for …

Satellite communication has the characteristics of wide coverage and large communication
capacity, and is not easily affected by land disasters. It is quite suitable as a supplement to …

In this paper, we investigate covert communication in an intelligent reflecting surface (IRS)-
assisted non-orthogonal multiple access (NOMA) system, where a legitimate transmitter …

Covert communications hide the transmission of a message from a watchful adversary while
ensuring a certain decoding performance at the receiver. In this paper, a wireless …

This article investigates the intelligent reflecting surface (IRS)-aided multi-antenna covert
communications. In particular, with the help of an IRS, a favorable communication …

Unmanned aerial vehicles (UAVs) are envisioned to be extensively employed for assisting
wireless communications in the Internet of Things (IoT). On the other hand, terahertz (THz) …

We investigate covert wireless communication in a multi-antenna relay network, where the
relay transmits its own covert message to the destination when assisting the source's …

Considering multi-user downlink ultra-high reliability and low latency communications
(URLLC), this paper employs the artificial noise (AN) technique to establish a secure and …

Covert communication can hide the information transmission process from the warden to
prevent adversarial eavesdropping. However, it becomes challenging when the location of …

In this paper, we consider the problem of full-duplex covert millimeter wave (mmWave)
communications, where a mmWave transmitter (Alice) sends information signals to its …
