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 …

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) …

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 …

This paper presents a unicast beamforming network for covert ambient backscatter
communications (AmBC). Different from the prior covert backscatter works using artificial …

This paper investigates the fundamental covert rate performance in a wireless relaying
system consisting of a source-destination pair, a full-duplex (FD) relay and a warden, where …

Future wireless communication systems will evolve toward multifunctional integrated
systems to improve spectrum utilization and reduce equipment sizes. Joint radar and …

This article investigates the covertness and secrecy of wireless communications in an
untrusted relay-assisted device-to-device (D2D) network consisting of a full-duplex base …

In this paper, we consider a common unicast beamforming network where Alice utilizes the
communication to Carol as a cover and covertly transmits a message to Bob without being …

Communication performance relies largely on the availability of channel state information
(CSI). This paper investigates the impact of outdated CSI on the achievable covert …

We explore leveraging the multiplicity of overt (public) messages, destined for different
receivers through different channels, for hiding the transmission of a covert (private) …
