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 …

Physical layer security is a promising approach that can benefit traditional encryption
methods. The idea of physical layer security is to take advantage of the propagation …

This paper proposes a new design of non-orthogonal multiple access (NOMA) under
secrecy considerations. We focus on a NOMA system, where a transmitter sends confidential …

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 …

Communication secrecy in the wireless systems has unique challenges due to broadcasting
nature of the radio waves, as compared to its wire-line counterpart. At the same time …

Due to the open nature of wireless communication systems, the data transmission over
these networks are vulnerable to malicious attack. To safeguard the transmitted data …

We propose a novel artificial noise (AN) injection scheme for wireless systems over quasi-
static fading channels, in which a single-antenna transmitter sends confidential messages to …

Motivated to understand the increasingly severe threat of unmanned aerial vehicles (UAVs)
to the confidentiality of terrestrial radio links, this paper analyzes the ergodic and E-outage …

Recently, the physical layer has gained a more prominent role on the security context of
wireless networks due to its potentiality on providing more effective solutions to safeguard …

In this paper, the secrecy performance of single-input-multiple-output systems over
correlated κ-μ shadowed fading channels is investigated. In particular, based on the classic …
