As a complement to high-layer encryption techniques, physical layer security has been
widely recognized as a promising way to enhance wireless security by exploiting the …

Physical layer security (PLS) has been extensively explored as an alternative to
conventional cryptographic schemes for securing wireless links. Many studies have shown …

In this paper, a random frequency diverse array-based directional modulation with artificial
noise (RFDA-DM-AN) scheme is proposed to enhance physical layer security of wireless …

Radio frequency (RF) based wireless power transfer provides an attractive solution to
extend the lifetime of power-constrained wireless sensor networks. Through harvesting RF …

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 …

The security of the Internet of Things (IoT) is receiving considerable interest as the low
power constraints and complexity features of many IoT devices are limiting the use of …

We enhance the physical layer security (PLS) of amplify-and-forward (AF) relaying networks
with the aid of joint relay and jammer selection (JRJS), despite the deleterious effect of …

Pilot contamination attack (PCA) in a time division duplex wireless communication system is
considered, where an eavesdropper (Eve) attacks the reverse pilot transmission phase in …

This paper studies the use of multi-antenna harvest-and-jam (HJ) helpers in a multi-antenna
amplify-and-forward (AF) relay wiretap channel assuming that the direct link between the …

This paper proposes a secure downlink multi-user transmission scheme enabled by a
flexible unmanned aerial vehicle base station (UAV-BS) and non-orthogonal multiple access …
