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 …

Effective recognition of communication jamming is of vital importance in improving wireless
communication system's anti-jamming capability. Motivated by the major challenges that the …

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 …

Covert communication can hide the information transmission process from the warden to
prevent adversarial eavesdropping. However, it becomes challenging when the location of …

This work employs an unmanned aerial vehicle (UAV) as a jammer to aid a covert
communication from a transmitter Alice to a receiver Bob, where the UAV transmits artificial …

In this letter, we propose a novel energy-efficient covert wireless communication scheme
through probabilistic jamming, where a jammer probabilistically transmits artificial noise …

We consider that a transmitter covertly communicates with multiple receivers under the help
of a friendly jammer. The messages intended for different receivers are transmitted in …

Covert communication, also known as communication with low probability of detection, aims
to provide reliable communication for legal users and prevent any other user from detecting …

In this work, we design a covert jamming scheme against an intelligent Eve towards physical
layer security in a cooperative cognitive radio networks. To protect the primary message …

In this paper, we investigate the realization of covert communication in a general radar-
communication cooperation system, which includes integrated sensing and communications …
