The open nature of radio propagation enables ubiquitous wireless communication. This
allows for seamless data transmission. However, unauthorized users may pose a threat to …

In this paper, we study physical layer security for the downlink of cellular networks, where
the confidential messages transmitted to each mobile user can be eavesdropped by both; 1) …

Cyber-security threats and issues have been exponentially increasing over the last two
decades, including in cognitive radio networks. These attacks and vulnerabilities negatively …

Interference alignment (IA) is a remarkable technique to manage interference, and artificial
noise (AN) can be utilized to combat one main threat of security, passive eavesdropping …

In this paper, we initially investigate the physical layer security over device-to-device
communications, where the channel is modeled from the Fisher-Snedecor. T distribution. To …

In this paper, we study the performance of multiuser single-input multiple-output mixed radio
frequency (RF)/free space optical (FSO) relay network with opportunistic user scheduling …

Cyber-physical systems such as autonomous vehicle networks are considered to be critical
infrastructures in various applications. However, their mission critical deployment makes …

This paper focuses on the QoS-aware secure routing design based on the physical layer
security technology for a multi-hop wireless network consisting of legitimate nodes …

The wireless medium offers many opportunities for broadcast communications. However, it
also opens the possibility for attackers to eavesdrop the broadcast data or to pretend to be …

In this paper, we propose a new wireless communication transmission architecture called
switched phased-array (SPA), to enhance physical layer security. SPA works as a platform …
