This paper provides a comprehensive review of the domain of physical layer security in
multiuser wireless networks. The essential premise of physical layer security is to enable the …

This tutorial reviews fundamental contributions to information security. An integrative
viewpoint is taken that explains the security metrics, including secrecy, privacy, and others …

This article studies the physical layer security in a multiple-input-multiple-output (MIMO) dual-
functional radar-communication (DFRC) system, which communicates with downlink cellular …

This paper studies secrecy rate optimization in a wireless network with a single-antenna
source, a multi-antenna destination and a multi-antenna eavesdropper. This is an …

In this paper, we consider physical layer security provisioning in multicell massive multiple-
input-multiple-output (MIMO) systems. Specifically, we consider secure downlink …

In this paper, we address the security of a two-way relay network in the presence of an
eavesdropper, where each node is only equipped with single antenna. We propose two …

We consider the communication scenario where a source-destination pair wishes to keep
the information secret from a relay node despite wanting to enlist its help. For this scenario …

Physical-layer security utilizes resources of the transmission medium to guarantee secure
communication against an adversary with unlimited computational power. Rooted in …

In this paper, we pioneer the study of physical-layer security in heterogeneous networks
(HetNets). We investigate secure communications in a two-tier downlink HetNet, which …

In this paper, we propose a linear precoder for the downlink of a multi-user MIMO system
with multiple users that potentially act as eavesdroppers. The proposed precoder is based …
