Due to the malicious attacks in wireless networks, physical layer security has attracted
increasing concerns from both academia and industry. The research on physical layer …

This paper provides a comprehensive review of the domain of physical layer security in
multiuser wireless networks. The essential premise of physical layer security is to enable the …

Non-orthogonal multiple access (NOMA) has been widely recognized as a promising way to
scale up the number of users, enhance the spectral efficiency, and improve the user-fairness …

We propose and analyze transmit antenna selection (TAS) to enhance physical layer
security in a wiretap channel with NA antennas at the transmitter, NB antennas at the …

We investigate the impact of cochannel interference on the security performance of multiple
amplify-and-forward (AF) relaying networks, where N intermediate AF relays assist the data …

Security at the physical layer (PHY) is a salient research topic in wireless systems, and
machine learning (ML) is emerging as a powerful tool for providing new data-driven security …

The communication between two legitimate peers in the presence of an external
eavesdropper is studied from a physical-layer security perspective in the context of free …

Cognitive radio has emerged as an essential recipe for future high-capacity, high-coverage
multitier hierarchical networks. Securing data transmission in these networks is of the utmost …

This paper investigates the secure transmission in downlink cell-free massive multiple-input
multiple-output (MIMO) systems in the presence of an active multi-antenna eavesdropper …

We analyze the impact of antenna correlation on secrecy performance of multiple-input
multiple-output wiretap channels where transmitter employs transmit antenna selection …
