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 …

Physical layer security (PLS) has been extensively explored as an alternative to
conventional cryptographic schemes for securing wireless links. Many studies have shown …

Physical layer security which safeguards data confidentiality based on the information-
theoretic approaches has received significant research interest recently. The key idea …

In this letter, we propose intelligent reflecting surface (IRS) aided multi-antenna physical
layer security. We present a power efficient scheme to design the secure transmit power …

Device-to-device (D2D) communication presents a new paradigm in mobile networking to
facilitate data exchange between physically proximate devices. The development of D2D is …

Wireless networks with their ubiquitous applications have become an indispensable part of
our daily lives. Wireless networks demand more and more spectral resources to support the …

This paper investigates the impact of intelligent reflecting surface (IRS) enabled wireless
secure transmission. Specifically, an IRS is deployed to assist multiple-input multiple-output …

We propose and analyze secret key generation using intelligent reflecting surface (IRS)
assisted wireless communication networks. To this end, we first formulate the minimum …

This paper proposes a multi-agent deep reinforcement learning-based buffer-aided relay
selection scheme for an intelligent reflecting surface (IRS)-assisted secure cooperative …

This paper investigates a full-duplex (FD) secure communication system with the assistance
of an intelligent reflecting surface (IRS). Compared with the traditional FD system, the IRS …
