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 …

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(CRN) with outdated channel state information (CSI) for two practical scenarios, ie, scenario …

In this paper, physical-layer security (PLS) for an underlay cognitive radio network (CRN)
over cascaded Rayleigh fading channels is studied. The underlying cognitive radio system …

This paper investigates the secrecy performance of a single-input multiple-output (SIMO)
based underlay cognitive radio networks. In particular, a single-antenna secondary …

We examine the secrecy performance of the receive antenna selection scheme in
interference-limited underlay cognitive radio network (CRN) where the antenna that results …

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underlay cognitive radio network (CRN) with outdated channel state information (CSI).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 …

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 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 …

In this paper, we investigate the secrecy performance of a Cooperative Cognitive Radio
Network (CCRN) in the presence of an eavesdropper (EAV). The secondary users (SUs) are …
