In this work, we design a covert jamming scheme against an intelligent Eve towards physical
layer security in a cooperative cognitive radio networks. To protect the primary message …

We consider physical-layer security in a novel MISO cooperative overlay cognitive radio
network (CRN) with a single eavesdropper. We aim to design an artificial noise (AN) aided …

In this study, the authors investigate the problem of jammer selection (JS) for enhancing the
secrecy goodput in a cooperative cognitive radio network with the multiple‐input–multiple …

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 …

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(CRN) with outdated channel state information (CSI) for two practical scenarios, ie, scenario …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 study, secure communication in cognitive radio networks is investigated. A
cooperative jammer is utilised to transmit artificial noise for interfering with the …

This paper investigates cooperative security in wireless networks, where a source (Alice)
intends to transmit a confidential message to a legitimate destination (Bob), with the help of …

In this paper, we consider a centralized cooperative cognitive radio network (CCRN), where
a primary base station sends a message to a primary user. Meanwhile, a secondary user …

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 …

In this letter, we consider an underlay cognitive radio network in which a secondary
transmitter (ST) communicates with a secondary destination (SD) with the aid of multiple …
