Reconfigurable intelligent surface (RIS) has been introduced as a promising emerging
paradigm to design a smart radio environment for improving wireless capacity. It has the …

In this paper, we study a secure cooperative transmission system in which a transmitter
(Alice) intends to send a secret message to an authorized receiver (Bob), with the aid of a …

We investigate the physical layer security of a relay-assisted underlay cognitive radio
network with simultaneous wireless information and power transfer (SWIPT). To this end, we …

This paper analyzes the physical layer security for cognitive relay networks under the peak
interference power constraint of the primary user receiver. In particular, a secondary user …

In this letter, we consider an underlay cognitive radio network in which a secondary
transmitter (ST) communicates with a secondary destination (SD) with the aid of multiple …

Due to the requirement of real time controlling on the vehicular ad-hoc networks (VANETs),
the security measure should be fast, lightweight, and strong. In this paper, we investigate the …

With fast growth of wireless services, secrecy has become an increasingly important issue
for wireless networks. In this paper, we investigate the secrecy capacity of the primary …

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, the physical-layer security (PLS) for an underlay cognitive radio network (CRN)
with multiple non-colluding eavesdroppers is studied. We assume that a secondary user …

In this paper, we analyze the tradeoff between outage probability (OP) and intercept
probability (IP) for a multi‐hop relaying scheme in cognitive radio (CR) networks. In the …
