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 …

This article considers an artificial noise (AN)-aided secure MIMO wireless communication
system. To enhance the system security performance, the advanced intelligent reflecting …

Due to the broadcast nature of radio propagation, the wireless air interface is open and
accessible to both authorized and illegitimate users. This completely differs from a wired …

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 …

Interference is traditionally viewed as a performance limiting factor in wireless
communication systems, which is to be minimized or mitigated. Nevertheless, a recent line of …

In this paper, we investigate the design of robust and secure transmission in intelligent
reflecting surface (IRS) aided wireless communication systems. In particular, a multi-antenna …

This article studies the physical layer security in a multiple-input-multiple-output (MIMO) dual-
functional radar-communication (DFRC) system, which communicates with downlink cellular …

Due to the malicious attacks in wireless networks, physical layer security has attracted
increasing concerns from both academia and industry. The research on physical layer …
