In this paper, we study the physical layer security for underlay cognitive radio network in the
presence of an eavesdropper that tries to intercept the secondary transmission. Specifically …

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 …

Wireless communication systems are vulnerable to eavesdropping attack in which the
attacker overhear the transmitted data in the network. Hence, the physical-layer security is of …

The paper investigates a decode-and-forward buffer-aided relay selection for an underlay
cognitive radio network in the presence of an eavesdropper. The secondary users operating …

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 …

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 …

This paper analyzes the physical layer security for cognitive relay networks under the peak
interference power constraint of the primary user receiver. In particular, a secondary user …

In this paper, the security performance of a dual-hop underlay cognitive radio (CR) system is
investigated. In this system, we consider that the transmitted information by a source node S …

In this paper, we study physical layer security in an underlay cognitive radio (CR) network.
We consider the problem of secure communication between a secondary transmitter …

In this paper, we investigate the secrecy outage probability in a dual-hop decode-and-
forward (DF) secondary cognitive radio network, which is equipped with one source, one …
