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, physical-layer security (PLS) for an underlay cognitive radio network (CRN)
over cascaded Rayleigh fading channels is studied. The underlying cognitive radio system …

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

In this paper, we introduce a new cooperative paradigm for secure communication in
cognitive radio networks (CRNs) where secondary users (SUs) are allowed to access the …

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 present a method of utilizing channel diversity to improve the secrecy
outage probability and the intercept probability in a cognitive radio (CR) network. With the …

In this paper, a physical-layer-security scheme for an underlay relay-based cognitive radio
network (CRN) that uses orthogonal frequency-division multiplexing (OFDM) as the medium …

In this paper, we propose physical layer security for cooperative cognitive radio networks
(CCRNs) with relay selection in the presence of multiple primary users and multiple …

In this paper, the physical layer security of a dual-hop underlay uplink cognitive radio
network is investigated over Nakagami-m fading channels. Specifically, multiple secondary …
