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 …

The performance of wireless communication network is important in emergency rescue
operations while ensuring optimum usage of limited wireless resources. Due to the …

This letter investigates covert communication in an intelligent reflecting surface (IRS)-
assisted system. We propose a novel algorithm that jointly optimizes the transmission …

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 This paper investigates the impact of outdated CSI on the achievable covert …

In practice, Internet of Things (IoT) applications may face two different hostile attacks, ie,
overhearing the broadcasted data and detecting the presence of data communication …

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 …

This paper examines integrating jamming and secondary signals for covert communications
in cognitive radio networks (CRNs), aiming to enhance covertness by using jamming and …

This paper investigates the covert communication in an air-to-ground (A2G) system, where a
UAV (Alice) can adopt the omnidirectional microwave (OM) or directional mmWave (DM) …

Unmanned aerial vehicle (UAV)-aided Terahertz (THz) relay systems can provide high-
speed wireless line-of-sight (LoS) communications at THz bands, which are envisioned as a …

Physical layer security is a common concern in dual-function radar communications (DFRC)
because of sharing of information between different emitters. We study covert …
