We study the physical-layer security of a cognitive radio system in the face of multiple
eavesdroppers (EDs), which is composed of a secondary base station (SBS), multiple …

In this paper, we study on two different strategies-jamming and cooperation–for improving
physical layer security in multi-tag ambient backscatter communications, which utilize …

This paper investigates the secure transmission in multiple access wiretap channels, where
multiple legitimate users transmit private information to an intended receiver in the presence …

In this paper, we propose an artificial noise-aided tag scheduling (ANTS) scheme in order to
enhance physical layer security in ambient backscatter communications (ABCs), which …

The security of the physical layer promises to provide secrecy for wireless communication.
The chaotic direct sequence spread spectrum (chaotic-DSSS) is one of the distinguished …

In this paper, we propose a secure modulation technique based on constellation map**
obfuscation to harden computational complexity for security at the physical-layer. To …

This paper investigates the problem of maximizing the secrecy energy efficiency (SEE) for
unmanned aerial vehicle‐(UAV‐) to‐ground wireless communication system, in which a …

In this paper, we investigate two user scheduling algorithms (optimal user and threshold-
based user scheduling algorithms) when we consider potential eavesdroppers in an uplink …

In this correspondence paper, we propose a secure user scheduling scheme, which selects
a user for data transmission and an extra user for artificial noise generation in a multiuser …

Physical-layer security (PLS) has attracted much attention in wireless communications and
has been considered one of the main candidates for enhancing wireless security in future …
