In this paper, we investigate physical layer security for multiple decode-and-forward (DF)
relaying underlay cognitive radio networks (CRNs) with fixed transmit power at the …

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 …

In this paper, we investigate the secrecy outage probability (SOP) for the cooperative
decode-and-forward (DF) underlay cognitive radio networks (CRNs). Duo to the spectrum …

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 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 …

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 …

This paper studies the physical layer security in cognitive relay network (CRN) with multiple
antennas in the presence of multiple eavesdroppers. Under spectrum sharing scenario and …

In this paper, we consider a multi-hop decode-and-forward (DF) relaying transmission in
underlay cognitive radio networks. Considering the presence of an eavesdropper that …

This paper investigates the secrecy performance of amplify-and-forward (AF)-relaying
cooperative cognitive radio networks (CCRNs) over Rayleigh-fading channels. Specifically …

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 …
