Unmanned aerial vehicles (UAVs) have found widespread commercial, civilian, and military
applications. Wireless communication has always been one of the core technologies for …

The concept of physical layer security builds on the pivotal idea of turning the channel's
imperfections, such as noise and fading, into a source of security. This is established …

This paper investigates the physical layer security of non-orthogonal multiple access
(NOMA) in large-scale networks with invoking stochastic geometry. Both single-antenna and …

Cyber-physical systems (CPS) offer integrated resolutions for various applications by
combining computer and physical components and enabling individual machines to work …

This paper studies multi-antenna-aided covert communications coexisting with randomly
located wardens and interferers, considering both centralized and distributed antenna …

The heterogeneous cellular network (HCN) is a promising approach to the deployment of 5G
cellular networks. This paper comprehensively studies physical layer security in a multitier …

This correspondence studies a new secrecy beamforming (SBF) scheme for multiple-input
single-output non-orthogonal multiple access (MISO-NOMA) systems. In particular, the …

Recent studies show that millimeter wave (mmWave) communications can offer orders of
magnitude, which increases in the cellular capacity. However, the secrecy performance of …

Wireless networks with directional antennas, like millimeter wave (mmWave) networks, have
enhanced security. For a large-scale mmWave ad hoc network in which eavesdroppers are …

In this paper, we study the secure multi-antenna transmission with artificial noise (AN) under
slow fading channels coexisting with randomly located eavesdroppers. We provide a …
