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 …

LPD communication has recently emerged as a new transmission technology to address
privacy and security in wireless networks. Recent studies have established the fundamental …

Recent work has established that when transmitter Alice wishes to communicate reliably to
recipient Bob without detection by warden Willie, with additive white Gaussian noise …

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 …

We consider the situation in which a transmitter attempts to communicate reliably over a
discrete memoryless channel, while simultaneously ensuring covertness (low probability of …

This tutorial reviews fundamental contributions to information security. An integrative
viewpoint is taken that explains the security metrics, including secrecy, privacy, and others …

In this paper, we study delay-intolerant covert communications in additive white Gaussian
noise (AWGN) channels with a finite block length, ie, a finite number of channel uses …

In this paper, we study covert communications between a pair of legitimate transmitter-
receiver against a watchful warden over slow fading channels. There coexist multiple …

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

The deployment of unmanned aerial vehicle (UAV) for surveillance and monitoring gives
rise to the confidential information leakage challenge in both civilian and military …
