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 …

We exploit both covert communication and friendly jamming to propose a friendly jamming-
assisted covert communication and use it to doubly secure a large-scale device-to-device …

Internet of Things (IoT) play a paramount role in every aspect of our daily lives. Due to more
diverse human needs, the future IoT networks are expected to be highly dynamic and …

Covert communication is capable of enhancing user privacy by protecting communication
behavior. In this article, by employing overlay and underlay spectrum access modes, we …

This work investigates wireless covert communication in a multi-sensor asymmetric noise
scenario. We adopt KL (Kullback–Leibler) divergence as the covertness constraint metric …

We leverage covert communication to enhance the security of a large-scale multi-tier Low
Earth Orbit (LEO) satellite network against vigilant adversarial terrestrial Base Stations (BSs) …

In this paper, we study a covert communication strategy based on non-ideal detection on
overt channels in Internet of Things (IoT) networks, where IoT device utilizes existing overt …

In this paper, a spectrum mask-based covert communication strategy is proposed in the multi-
antenna network. By adopting the transmission strategy of that using maximum ratio …
