This study investigates the physical‐layer security in random cognitive radio network (CRN)
consisting of randomly distributed primary nodes, secondary nodes, relay nodes and …

We consider a cognitive radio (CR) network consisting of a secondary transmitter (ST), a
secondary destination (SD) and multiple secondary relays (SRs) in the presence of an …

In this paper, we propose physical layer security for cooperative cognitive radio networks
(CCRNs) with relay selection in the presence of multiple primary users and multiple …

Spectrum efficiency (SE) and energy efficiency (EE) in secure communications have
attracted much attention recently due to the fact that future wireless networks need to …

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 …

Cognitive radio networks using relays have been introduced to enhance secondary network
performance by having secondary users (SUs) transmit in two hops. This paper develops a …

In this paper, the problem of communication security in an underlay wiretap cognitive radio
network is addressed and statistically investigated. We rely on a simple dual-hop …

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, the physical layer security in cognitive radio networks (CRNs) is investigated.
We consider an underlay relay assisted CRN consisting of multiple secondary sources …

The security in cognitive radio networks (CRNs) has been attracting continuously growing
attention, due to the open and dynamic nature of cognitive radio architecture. In this paper …
