This letter investigates secrecy performance for cognitive transmissions, where a secondary
user (SU) shares same spectrum with a primary user (PU) simultaneously ensuring the …

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 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, 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 …

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 …

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 investigate the power allocation of primary base station (PBS) and
cognitive base station (CBS) across different orthogonal frequency division multiplexing …

Physical layer security (PLS) techniques are increasingly being employed to secure
transmissions in wireless networks. Unlike traditional cryptography-based methods, PLS is …

In this paper, we consider a secrecy transmission scheme based on physical layer,
employing multi-band transmitters with dynamic power allocations and channel selections …

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 …
