As a complement to high-layer encryption techniques, physical layer security has been
widely recognized as a promising way to enhance wireless security by exploiting the …

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 …

This paper studies the design of artificial-noise-aided (AN-aided) secure transmission in
slow-fading multiple-input–single-output (MISO) channels. We consider the scenario where …

This paper investigates the physical layer security in a multiple-input-single-output multicast
channel, where a common message is transmitted to multiple receivers and only statistical …

The issue of physical layer security for single-input-multiple-output (SIMO) wiretap channel
with uncoordinated cooperative jamming (UCJ) is addressed in this letter, and we focus on …

This letter proposes a new efficient yet simple distributed ordered-based jamming scheme
for securing a legitimate transmission and powering a wireless receiver equipped with a …

This paper studies the secure transmission in a multiuser broadcast channel where only the
statistical channel state information of the eavesdropper is available. We propose to apply …

In this paper, we investigate the physical-layer security of slow fading wiretap channel with
channel estimation errors. We aim to maximize the reliable secrecy rate under constraints of …

A practical uncoordinated cooperative jamming (UCJ) scheme with multiple single-antenna
helpers is proposed in this paper to enhance the physical layer security of single-input …

This paper studies the artificial noise (AN) aided secure transmission design in a multiple-
input-single-output multicast channel where a common message is transmitted to multiple …
