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 …

Data encryption aims to protect the confidentiality of data at storage, during transmission, or
while in processing. However, it is not always the optimum choice as attackers know the …

Covert communications hide the transmission of a message from a watchful adversary while
ensuring a certain decoding performance at the receiver. In this paper, a wireless …

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

This paper studies multi-antenna-aided covert communications coexisting with randomly
located wardens and interferers, considering both centralized and distributed antenna …

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) …

Despite the recency of their conception, Generative Adversarial Networks (GANs) constitute
an extensively-researched machine learning sub-field for the creation of synthetic data …

Unmanned aerial vehicles (UAVs) have attracted a lot of research attention because of their
high mobility and low cost in serving as temporary aerial base stations (BSs) and providing …

With growing security threats to the evolving wireless systems, protecting user privacy
becomes progressively challenging. Even if the transmitted information is encrypted and the …

In this letter, we develop a new framework to jointly characterize covertness and timeliness
of short-packet communications, in which a new metric named covert age of information …
