In this article we explore the security issues on physical layer for cognitive radio networks.
First we give an overview on several existing security attacks to the physical layer in …

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 …

Recent developments of wireless communication lead to the problem of growing spectrum
shortage. Cognitive radio, as a novel technology, tends to solve this problem by dynamically …

This article investigates the physical-layer security of CR networks, which are vulnerable to
various newly arising attacks targeting the weaknesses of CR communications and …

In this paper, we consider a cognitive radio network that consists of one cognitive base
station (CBS) and multiple cognitive users (CUs) in the presence of multiple eavesdroppers …

This paper discusses the topic of wireless security in cognitive radio networks, delineating
the key challenges in this area. With the ever-increasing scarcity of spectrum, cognitive …

In this paper, we study physical layer security in an underlay cognitive radio (CR) network.
We consider the problem of secure communication between a secondary transmitter …

In the last decade, cognitive radio (CR) has emerged as a major next generation wireless
networking technology, which is the most promising candidate solution to solve the spectrum …

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

In this paper, we investigate secrecy capacity of a cognitive radio network based on
stochastic geometry distributions. We consider the Poisson process of both the secondary …
