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 …

Resiliency against eavesdropping and other security threats has become one of the key
design considerations for communication systems. As wireless systems become ubiquitous …

Cyber attacks on the OSI layers are a growing concern, targeting various aspects of
communication networks and systems. Each layer of the OSI model is susceptible to specific …

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

The industrial environment poses strict requirements to the infrastructure of good and
service production and delivery. Communications are not an exception. Wired systems …

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 …

The advanced features of 5G mobile wireless network systems yield new security
requirements and challenges. This paper presents a comprehensive study on the security of …

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 …

Non-orthogonal multiple access (NOMA) has been widely recognized as a promising way to
scale up the number of users, enhance the spectral efficiency, and improve the user-fairness …

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 …
