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 …

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 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 …

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 …

We look into adopting improper Gaussian signaling (IGS) in order to enhance the secrecy
performance of an underlay cognitive radio network since in interference-limited networks …

In this paper, the secure communication of a cognitive radio network (CRN) over Nakagami-
m fading channel is investigated. An underlay protocol is used in the considered network …

This letter investigates secure communications against eavesdropping in an underlay
cognitive radio network. The secondary users do not know the interference level that they …

This paper investigates the secrecy performance of an underlay cognitive radio network
(CRN) with outdated channel state information (CSI) for two practical scenarios, ie, scenario …

This work explores the physical layer security of an underlay cognitive radio network (CRN)
in the presence of a powerful interferer called a primary transmitter (PT) under peak …

In this article, we derive the Secrecy Outage Probability (SOP) and the Probability of Strictly
Positive Secrecy Capacity (SPSC) for Cognitive Radio Networks with Adaptive Transmit …
