Considering multi-user downlink ultra-high reliability and low latency communications
(URLLC), this paper employs the artificial noise (AN) technique to establish a secure and …

We study, in this paper, the secrecy performance of a multi-user (MU) multiple-input single-
output visible light communication broadcast channel with confidential messages. The …

We consider covert communication, ie, hiding the presence of communication from an
adversary for multiple-input multiple-output (MIMO) additive white Gaussian noise (AWGN) …

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

In this paper, we consider the broadcast channel with confidential messages and external
eavesdroppers (BCCE), where a multi-antenna base station simultaneously communicates …

We consider that a transmitter covertly communicates with multiple receivers under the help
of a friendly jammer. The messages intended for different receivers are transmitted in …

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 paper, we analyze the performance of regularized channel inversion (RCI) precoding
in multiple-input single-output (MISO) broadcast channels with confidential messages under …

We study the optimality of linear precoding for the two-receiver multiple-input multiple-output
(MIMO) Gaussian broadcast channel (BC) with confidential messages. Secret dirty-paper …
