This letter studies and compares the physical-layer security approach and the covert
communication approach for a wiretap channel with a transmitter, an intended receiver and …

Information-theoretic secrecy, in particular the wiretap channel formulation, provides
protection against interception of a message by adversary Eve and has been widely studied …

In practice, Internet of Things (IoT) applications may face two different hostile attacks, ie,
overhearing the broadcasted data and detecting the presence of data communication …

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 …

This article explores a new secure wireless communication scenario for the data collection
in the Internet of Things (IoT) where the physical layer security technology is applied to …

In this article, we investigate joint information-theoretic secrecy and covert communication in
a single-input-multioutput (SIMO) system where a transmitter (Alice) is communicating with …

In this letter, we investigate covert communications with finite blocklength under the channel
inversion power control (CIPC) scheme, where a transmitter is allowed to communicate with …

A covert communication system under block fading channels is considered, where users
experience uncertainty about their channel knowledge. The transmitter seeks to hide the …

Covert communication aims to hide the existence of the transmissions to guarantee the
security in wireless communications. In this letter, channel uncertainty is exploited to achieve …

This paper investigates the achievable message transmission rate of covert communication
over slow fading channels where the channel coefficient remains unchanged over a finite …
