In this correspondence paper, we investigate the security and efficiency of data transmission
for overlay cognitive radio networks, which consist of a pair of primary users, multiple pairs of …

This work investigates the secrecy capability of energy harvesting based overlay cognitive
networks (EHOCNs). To this end, we assume that a message by a licensed transmitter is …

In this paper, we examine the physical (PHY) layer security in terms of secrecy outage of an
energy harvesting (EH) relay based underlay cognitive radio network (CRN) in the presence …

In cognitive radio networks, direct communications between a primary sender–recipient pair
may be blocked due to uncertainties such as deep fading. Therefore, this paper studies …

In this paper, we propose a destination-aided jamming scheme for secrecy simultaneous
wireless information and power transfer (SWIPT) in cognitive relay networks. In which, an …

In this paper, we study the secure communication of cognitive energy harvesting relay
networks when there exist multiple eavesdroppers who can overhear the message of the …

This paper investigates the physical layer security of an underlay cognitive radio network
with relay selection scheme under threats of an eavesdropper. We consider a set of …

In this letter, we consider a secure underlay cognitive radio network consisting of a
secondary source-destination pair and a primary transmitter-receiver pair in the presence of …

Security is considered a critical issue in the deployment of 5G networks because of the
vulnerability of information that can be intercepted by eavesdroppers in wireless …

Physical-layer security (PLS) for an underlay cognitive radio network (CRN)-based
simultaneous wireless information and power transfer (SWIPT) over cascaded κ-µ fading …
