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

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 …

This paper considers the problem of covert communication over a multiple-input single-
output channel (MISO) in the case of the imperfect channel state information. The transmitter …

In this paper, we address the problem of joint covert communication and secure
transmission in untrusted relaying networks when multiple wardens exist in the network. We …

Covert communications can hide the very existence of wireless transmissions and thus are
able to address privacy issues in numerous applications of the emerging Internet of Things …

In this paper, we study a novel joint information-theoretic secrecy and covertness model for
an unmanned aerial vehicle (UAV)-assisted finite blocklength transmission system, in which …

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 …

Covert communication can hide the information transmission process from the warden to
prevent adversarial eavesdropping. However, it becomes challenging when the location of …

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 …
