Physical layer security (PLS) has emerged as a new concept and powerful alternative that
can complement and may even replace encryption-based approaches, which entail many …

This paper considers improving the confidentiality of visible light communication (VLC) links
within the framework of physical-layer security. We study a VLC scenario with one …

Security has always played a critical role in wireless cooperative communication systems
design. Eavesdropping and jamming are two common threats to the information security in …

In this paper, we analyze the secrecy capacity of a half-duplex energy harvesting (EH)-
based multi-antenna amplify-and-forward relay network in the presence of a passive …

Recently, directional modulation has become an active research area in wireless
communications due to its security. Unlike existing research work, we consider a multi-beam …

Three relay selection techniques, aiming at achieving secure non-orthogonal multiple
access in cooperative energy-harvesting (EH) communications, are proposed and …

In order to enhance the secrecy performance of the generalized space shift keying (GSSK)
visible light communication (VLC) system, in this paper, an optical jamming-aided secrecy …

Power line communication (PLC) has enabled many smart grid applications and
functionalities over the past few years. Secure communications over such links however …

In this paper, we make an investigation of robust beamforming for secure directional
modulation in the multiuser multiple-input and multiple-output systems in the presence of …
