In this paper, we investigate secrecy capacity of a cognitive radio network based on
stochastic geometry distributions. We consider the Poisson process of both the secondary …

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 …

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, we consider the transmission of confidential information over a κ-μ fading
channel in the presence of an eavesdropper who also experiences κ-μ fading. In particular …

In this study, the authors investigate the physical‐layer security in a cognitive radio network
where both the secondary user (SU) and the primary user (PU) are facing security threats …

Next-generation wireless communication systems with high user mobility inherit cascaded
fading channel models, where the fading effects are more severe than classical channel …

In this paper, we investigate the secrecy outage performance of a dual-hop inter-vehicle
communication system, in which all nodes are in motion and all fading channels are …

We investigate the secrecy performance of an underlay small-cell cognitive radio network
under unreliable backhaul connections. The small-cell network shares the same spectrum …

In this paper, we consider a cooperative multi-hop secured transmission protocol to underlay
cognitive radio networks. In the proposed protocol, a secondary source attempts to transmit …

We look into adopting improper Gaussian signaling (IGS) in order to enhance the secrecy
performance of an underlay cognitive radio network since in interference-limited networks …
