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 …

Physical layer covert communication is a crucial secure communication technology that
enables a transmitter to convey information covertly to a recipient without being detected by …

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 …

In this article, we investigate covert communication in simultaneously transmitting and
reflecting reconfigurable intelligent surface (STAR-RIS)-assisted networks with rate-splitting …

In this paper, we study covert communications between a pair of legitimate transmitter-
receiver against a watchful warden over slow fading channels. There coexist multiple …

In this paper, we study delay-intolerant covert communications in additive white Gaussian
noise (AWGN) channels with a finite block length, ie, a finite number of channel uses …

This paper studies multi-antenna-aided covert communications coexisting with randomly
located wardens and interferers, considering both centralized and distributed antenna …

Unmanned aerial vehicles (UAVs) have attracted a lot of research attention because of their
high mobility and low cost in serving as temporary aerial base stations (BSs) and providing …

In this letter, we consider delay-constrained covert communications with the aid of a full-
duplex (FD) receiver. Without delay constraints, it has been shown that the transmit power 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 …
