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 …

In-band full-duplex (IBFD) transmission represents an attractive option for increasing the
throughput of wireless communication systems. A key challenge for IBFD transmission is …

Physical layer security which safeguards data confidentiality based on the information-
theoretic approaches has received significant research interest recently. The key idea …

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

It has been predicted that by the year 2030, 5G and beyond 5G (B5G) networks are
expected to provide hundreds of trillions of gigabytes of data for various emerging …

In recent times, security and privacy at the physical (PHY) layer has been a major issue of
several communication technologies which comprise the internet of things (IoT) and mostly …

This paper studies physical layer security in a wireless ad hoc network with numerous
legitimate transmitter-receiver pairs and eavesdroppers. A hybrid full-duplex (FD)/half …

Wireless communications have gained huge attention over the past decades because of
continuously increasing demands. The main goal of all wireless network designers is to …

Full-duplex communication enables simultaneous transmission from both ends of a
communication link, thereby promising significant performance gains. Generally, it has been …

In this article, a new relay-aided secure communication system is investigated, where a
transmitter sends signals to a destination via an amplify-and-forward (AF) relay in the …
