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 …

In this work, we aim to maximize the timeliness of data collection subject to a covertness
constraint in unmanned aerial vehicle (UAV)-aided Internet of Things (IoT) networks, where …

With the gradual promotion of the fifth generation (5G) mobile communication and Internet of
Things (IoT) applications, wireless communication transmission will be more vulnerable to …

This article investigates the covert performance of an unmanned aerial vehicle (UAV)
jammer-assisted cognitive radio (CR) network. In particular, the covert transmission of …

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 …

The broadcast nature of wireless communication systems makes wireless transmission
extremely susceptible to eavesdropping and even malicious interference. Physical layer …

Communication performance relies largely on the availability of channel state information
(CSI). This paper investigates the impact of outdated CSI on the achievable covert …

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

Covert communications, or covert channels, are commonly exploited to establish a data
exfiltration channel from an insider on a trusted network to a malicious receiver outside the …
