Reconfigurable intelligent surface (RIS) is considered as a promising technology, which can
effectively control the phase of signals with low-cost reflective elements. In this paper, we …

Reconfigurable intelligent surface (RIS) has been attracted lots of attention due to the fact
that it can reconfigure propagation environment with low cost for resource-constrained …

In this paper, secrecy performance is investigated over the cascaded fading channel for the
κ-μ distribution. The probability density function (PDF) and the cumulative distribution …

Physical layer security (PLS) has been proposed to afford an extra layer of security on top of
the conventional cryptographic techniques. Unlike the conventional complexity-based …

In this paper, the physical-layer security for a three-node wiretap system model is studied.
Under the threat of multiple eavesdroppers, it is presumed that a transmitter is …

Abstract 5G and future generation networks require physical layer security (PLS) to reinforce
the security at the higher communication layers. A novel technique of securely transmitting …

In contrary to Shannon's ergodic capacity, the delay-constrained effective rate is used to
define the maximum data rate of the real-time applications in 5G and beyond networks …

Herein, we consider an underlay cognitive radio network (CRN) where mobile secondary
user wishes to transmit a confidential information to the secondary destination in the …

The fifth-generation (5G) communications and beyond are expected to serve a huge number
of devices and services. However, due to the fixed spectrum allocation policies, the need for …

In a wireless network, it is necessary to make the security of the network so high that
eavesdroppers cannot intercept the messages. If a key message is divided into several …
