This article considers a covert wireless communication (CWC) scheme for multi-channel
wireless transmission systems with a full-duplex receiver. Specifically, the transmitter …

Covert communication aims at achieving a reliable communication while ensuring an
arbitrary small probability of being detected by the adversary. In this paper, we exploit the …

In this work, we propose a covert communication scheme where the transmitter attempts to
hide its transmission to a full-duplex receiver, from a warden that is to detect this covert …

Covert communication considers the ability of transmitter Alice to communicate reliably to
receiver Bob without being detected by warden Willie. Previous work has generally …

Covert wireless communication intends to prevent hostile surveillance but is threatened by
the powerful multi-antenna detection technique. In this paper, we investigate finite …

Covert communication promises a secure transmission mechanism for Backscatter
Communication (BC) by hiding the transmission behavior of backscatter devices from …

In this letter, we consider the covert wireless communication (CWC) against a jamming-
assisted proactive detector in two scenarios corresponding to whether Alice utilizes the …

We explore leveraging the multiplicity of overt (public) messages, destined for different
receivers through different channels, for hiding the transmission of a covert (private) …

In this letter, we propose a random sub-channel selection covert transmission (RSCT)
scheme in multi-channel systems to enhance the covertness of communication. We derive …

This paper explores a new secure wireless communication paradigm where the physical
layer security technology is applied to counteract both the detection and eavesdropping …
