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 …

This paper investigates data transmission and physical-layer secrecy in cognitive radio (CR)
networks. We propose to apply full-duplex transmission and dual antenna selection at a …

In this paper, we investigate the secondary network physical layer security under the outage
constraint of the primary user (PU) receiver and interference from the PU transmitter to the …

The presence of correlated and imperfect channel state information (CSI) affects the secrecy
performance of cognitive radio networks (CRN). In this paper, we propose a physical layer …

This study investigates the secrecy outage performance of a single‐input multiple‐output
underlay cognitive radio network (CRN) with outdated channel state information (CSI). The …

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 …

Herein, we consider an underlay cognitive radio network (CRN) where mobile secondary
user wishes to transmit a confidential information to the secondary destination in 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 …

In this study, the physical layer security for cognitive radio network (CRN) will be
investigated in which a secondary user transmitter (SU-Tx) sends confidential information to …

This paper investigates the physical-layer security (PLS) of a single-input-multiple-output
(SIMO) underlay cognitive radio network (CRN) over cascaded-fading channels. A …
