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 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 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 …

This study investigates the secrecy outage performance of a single‐input multiple‐output
underlay cognitive radio network (CRN) with outdated channel state information (CSI). 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 …

This paper investigates the secrecy performance of an underlay cognitive radio network
(CRN) with outdated channel state information (CSI) for two practical scenarios, ie, scenario …

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 …

The presence of correlated and imperfect channel state information (CSI) affects the secrecy
performance of cognitive radio networks (CRN). In this paper, we propose a physical layer …

This work explores the physical layer security of an underlay cognitive radio network (CRN)
in the presence of a powerful interferer called a primary transmitter (PT) under peak …

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 …
