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 …

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 …

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 …

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) …

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

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

The deployment of unmanned aerial vehicle (UAV) for surveillance and monitoring gives
rise to the confidential information leakage challenge in both civilian and military …

Covert wireless communication aims to hide the very existence of wireless transmissions in
order to guarantee a strong security in wireless networks. In this paper, we examine the …

Due to the open nature of wireless communication systems, the data transmission over
these networks are vulnerable to malicious attack. To safeguard the transmitted data …
