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 …

The authors study the secure transmission design in random cognitive radio networks where
the primary users, the secondary users and the eavesdroppers are randomly distributed …

With fast growth of wireless services, secrecy has become an increasingly important issue
for wireless networks. In this paper, we investigate the secrecy capacity of the primary …

This paper studies the physical layer security (PLS) in an underlay cognitive radio (CR)
network. Under an interference constraint set by the primary user, we propose a secure …

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 …

Wireless communication systems are vulnerable to eavesdropping attack in which the
attacker overhear the transmitted data in the network. Hence, the physical-layer security is of …

In this paper, we present a method of utilizing channel diversity to improve the secrecy
outage probability and the intercept probability in a cognitive radio (CR) network. With the …

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 …

Motivated by information-theoretic security, the Poisson model for secure connectivity in
stochastic networks has recently received great attention. Although several expressions for …

In this paper, we investigate the physical-layer security of a secure communication in single-
input multiple-output (SIMO) cognitive radio networks (CRNs) in the presence of two …
