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 address the challenge of establishing secure communication within a
symbiotic radio (SR) network. This network comprises a primary transmitter (PT), a primary …

This article studies the confidential transmission performance of an electric vehicle (EV) in
heterogeneous network when it communicates with vehicle to grid (V2G). Based on the relay …

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 …

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 article, the physical-layer security of a dual-hop unmanned aerial vehicle-based
wireless network, subject to imperfect channel state information (CSI) and mobility effects, is …

In this letter, we study the physical layer secrecy performance of the classic Wyner's wiretap
model over double Rayleigh fading channels for vehicular communications links. We derive …

In this paper, we consider a cognitive radio network that consists of one cognitive base
station (CBS) and multiple cognitive users (CUs) in the presence of multiple eavesdroppers …

Achieving secrecy in cognitive wireless networks is challenging due to the broadcast nature
of the propagation medium. This article introduces the concept of cognitive network secrecy …

In this paper, secure communication aided by a multiantenna cooperative jammer is
investigated. Under very practical but adverse assumptions, ie, no instantaneous jammer …
