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 …

In this paper, we investigate the secrecy performance of a Cooperative Cognitive Radio
Network (CCRN) in the presence of an eavesdropper (EAV). The secondary users (SUs) are …

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 performance achieved by a new cooperative
cognitive radio (CR) model which employs the two-path amplify-and-forward (AF) relaying …

In this paper, we propose and analyze an underlay cooperative cognitive network with
Physical Layer Security where a best relay is selected based on maximizing end-to-end …

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 …

In this study, the secrecy performance of cooperative half‐duplex cognitive relay networks
(CRNs) comprised of multiple primary users (PUs) and multiple eavesdroppers under the …

We consider a secure overlay cognitive radio network with an eavesdropper wherein a multi-
antenna secondary transmitter performs transmission in primary spectrum, on the condition …

In this, we propose a generalized partial relay selection (PRS) protocol to enhance the
secrecy performance for cooperative cognitive radio networks (CRNs) in terms of the …

This study evaluates the intercept and outage probability of a decode‐and‐forward (DF)
underlay cognitive radio network. The secondary users are subject to interference limitations …
