Due to its high speed and low latency, D2D communication plays an important role in
providing proximity data services in 5G systems, which may contain privacy sensitive data …

A device-to-device (D2D) communication link is vulnerable because it is relatively easy to be
compromised by adversaries due to the fact that D2D terminals are power limited nodes …

Device-to-device (D2D) communications underlaid cellular networks have emerged as a
promising network architecture to provide extended coverage and high data rate for various …

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

Covert communication is often limited in rate because it is difficult to hide the signal in the
background noise. Recent work has shown that jamming can significantly improve the rate …

Covert communication, also known as low probability of detection (LPD) communication,
prevents the adversary from knowing that a communication is taking place. Recent work has …

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 …

The integration of unmanned aerial vehicle (UAV) networks and device-to-device (D2D)
communications is expected to provide ubiquitous connectivity and high-speed rates for …

In this paper, we propose a covert wireless uplink transmission strategy in space-air-ground
integrated vehicular networks, where the source vehicle transmits its own message over the …

This letter studies a wireless covert communication system, where a jammer generating
intermittent artificial noise (AN) is employed to confuse the warden. The transmission …
