Physical layer security (PLS) has emerged as a new concept and powerful alternative that
can complement and may even replace encryption-based approaches, which entail many …

Physical layer security (PHY-security) takes the advantages of channel randomness nature
of transmission media to achieve communication confidentiality and authentication. Wiretap …

In this paper, we introduce an intelligent reflecting surface (IRS) to provide a programmable
wireless environment for physical layer security. By adjusting the reflecting coefficients, the …

In this paper, we propose to utilize intelligent reflecting surfaces (IRSs) for enhancing the
physical layer security of wireless communications systems. In particular, an IRS-assisted …

This paper provides a comprehensive review of the domain of physical layer security in
multiuser wireless networks. The essential premise of physical layer security is to enable the …

Physical (PHY) layer security approaches for wireless communications can prevent
eavesdrop** without upper layer data encryption. However, they are hampered by …

The capacity of the Gaussian wiretap channel model is analyzed when there are multiple
antennas at the sender, intended receiver and eavesdropper. The associated channel …

The dual use of radio signal for simultaneous wireless information and power transfer
(SWIPT) has recently drawn significant attention. To meet the practical requirement that the …

This paper studies secrecy rate optimization in a wireless network with a single-antenna
source, a multi-antenna destination and a multi-antenna eavesdropper. This is an …

We consider the MIMO wiretap channel, that is a MIMO broadcast channel where the
transmitter sends some confidential information to one user which is a legitimate receiver …
