In this paper, we investigate the secondary network physical layer security under the outage
constraint of the primary user (PU) receiver and interference from the PU transmitter to the …

In this paper, we consider a spectrum sharing cognitive radio network where a secondary
user (SU) transmitter (SU-Tx) communicates with multiple SU receivers (SU-Rxs). There …

In this paper, we investigate the physical-layer security of a secure communication in single-
input multiple-output (SIMO) cognitive radio networks (CRNs) in the presence of two …

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 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 …

We investigate the secrecy outage performance of maximal ratio combining (MRC) in
cognitive radio networks over Rayleigh fading channels. In a single-input multiple-output …

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 …

This paper investigates the physical-layer security (PLS) of a single-input-multiple-output
(SIMO) underlay cognitive radio network (CRN) over cascaded-fading channels. A …

In this paper, we consider a spectrum sharing cognitive radio network (CRN) in the presence
of an eavesdropper (EAV) who illegally listens to the primary user (PU) communication …

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 …
