In this paper, the physical-layer security (PLS) for an underlay cognitive radio network (CRN)
with multiple non-colluding eavesdroppers is studied. We assume that a secondary user …

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 …

In this paper, we investigate an overlay cognitive radio network (CRN) in which one user is
selected among multiple secondary users (SUs) to harvest energy from primary …

This work deals with the physical layer security performance of a dual-hop underwater
optical communication (UOWC)-radio frequency (RF) network under the intruding attempts …

In this paper, physical-layer security (PLS) of an underlay cognitive radio network (CRN)
operating over cascaded Rayleigh fading channels is examined. In this scenario, a …

Physical layer security (PLS) is investigated in a multiple-input multiple-output multiple-
antenna eavesdropper keyhole channel over Rayleigh fading. Specifically, the secrecy …

Cognitive radio networks (CRNs) are acknowledged for their ability to tackle the issue of
spectrum under-utilization. In the realm of CRNs, this paper investigates the energy …

In this study, physical layer security (PLS) in a dual-hop underwater optical wireless
communication (UOWC)-radio frequency (RF) network under the intruding attempts of …

Physical-layer security (PLS) is examined in this paper for an underlay cognitive radio
network (CRN). Two secondary users (SUs) interact through a relay that is equipped with …

In this paper, we consider information transmission over a three-node physical layer security
system. Based on the imperfect estimations of the main channel and the eavesdropping …
