Providing secure communications over the physical layer with the objective of achieving
secrecy without requiring a secret key has been receiving growing attention within the past …

Security is an issue of paramount importance, yet is it a significant challenge for wireless
communications, which becomes more intricate when facing a full duplex (FD) active …

We consider the physical layer security in a multi-user massive multiple-input multiple-output
system, where an eavesdropper (Eve) can intercept the information intended for any of the …

In antenna sequence spatial modulation (ASSM), the spatial and symbol domains are both
used to encode information. The sequencing of the antennas' transmissions within given …

The performance of next-generation wireless systems (5G/6G and beyond) at the physical
layer is primarily driven by the choice of digital modulation techniques that are bandwidth …

We investigate the transmission of a secret message from Alice to Bob in the presence of an
eavesdropper (Eve) and many of decode-and-forward relay nodes. Each link comprises a …

In this paper, we address physical layer security in multiple-input single-output (MISO)
wiretap channels in the presence of a passive eavesdropper. Artificial noise (AN) is used to …

Physical layer security (PLS) is an emerging paradigm that focuses on using the properties
of wireless communication, such as noise, fading, dispersion, interference, diversity, etc., to …

The achievable secrecy rate regions of various multi‐user channels with Gaussian inputs
are well‐known in the literature. To gain more practical insights into the achievable rates, it …

Wireless broadcast allows widespread and easy information transfer. However, it may
expose the information to unintended receivers, which could include eavesdroppers. As a …
