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 …

Satellite communication has the characteristics of wide coverage and large communication
capacity, and is not easily affected by land disasters. It is quite suitable as a supplement to …

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) …

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 …

This paper investigates covert communications with finite blocklength in the presence of
multiple randomly distributed wardens, which are modeled as a Poisson point process …

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

In this letter, we investigate covert communications in uplink non-orthogonal multiple access
(NOMA) systems, where a covert user tries to transmit private information to a legitimate …

In this article, we investigate covert millimeter-wave (mmWave) communications with finite
blocklength, where a multiantenna transmitter sends covert messages to a legitimate …

In this letter, we investigate covert communications with finite blocklength under the channel
inversion power control (CIPC) scheme, where a transmitter is allowed to communicate with …
