In this paper, we consider the secure beamforming design for an underlay cognitive radio
multiple-input single-output broadcast channel in the presence of multiple passive …

This paper considers secure communications for an underlay cognitive radio network (CRN)
in the presence of an external eavesdropper (Eve). The secrecy performance of CRNs is …

We consider a cognitive radio network where multiple secondary users (SUs) coexist with a
primary user (PU). There exist multiple eavesdroppers (EAVs) who attempt to overhear the …

We evaluate and quantify the joint effect of fading and multiple interferers on the physical-
layer (PHY) security of a system consisting of a base-station (BS), a legitimate user, and an …

This paper investigates the effect of multiuser gain provided by the secondary user selection
on the secrecy performance of the primary users. We first propose a simple scheme where …

In this paper, we propose a cooperative approach to improve the security of both primary
and secondary systems in cognitive radio multicast communications. During their access to …

For the modulation classification problems, the deep learning approaches can determine the
unknown modulation formats in high confidence. However, it has been maliciously used by …

A joint resource allocation policy for an underlay multi-user secure cognitive radio network
(CRN) adopting the time-division multiple-access scheme with the guarantee of the …

As a novel statistical model, Málaga distribution is proposed recently, which covers many
commonly used fading models as special cases. The secure transmission of information …

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 …
