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 …

This work examines the performance gain achieved by deploying an intelligent reflecting
surface (IRS) in covert communications. To this end, we formulate the joint design of the …

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 …

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 considers covert communications in the context of unmanned aerial vehicle
(UAV) networks, aiming to hide a UAV for transmitting critical information out of an area that …

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 …

This paper jointly optimizes the flying location and wireless communication transmit power
for an unmanned aerial vehicle (UAV) conducting covert operations. This is motivated by …

In this paper, we examine the optimality of Gaussian signalling for covert communications
with an upper bound on D (p 1|| p 0) or D (p 0|| p 1) as the covertness constraint, where D (p …
