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 propose covert beamforming design frameworks for integrated radar sensing and
communication (IRSC) systems, where the radar can covertly communicate with legitimate …

In this paper, we investigate the feasibility and performance of the covert communication
with a spectrum sharing relay in the finite blocklength regime. Specifically, the relay …

In this article, we investigate the design of the trajectory of an unmanned aerial vehicle
(UAV) and the transmit power of ground users to improve covert communications against a …

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

In this letter, we jointly investigate packet generation and covert communication in delay-
intolerant status update systems. For the first time, we establish a bridge between the prior …

Advancements in intelligent transportation necessitate a dependable medium access control
(MAC) protocol to enable high-priority safety broadcasts. Implementing cognitive radio …

In this work, we investigate short-packet covert communication in interweave cognitive radio
networks (CRNs), where a secondary transmitter (ST) opportunistically accesses the …

Extensive research attentions have been devoted to studying cooperative cognitive radio
networks (CCRNs), where secondary users (SU) providing cooperative transmissions can …
