This paper examines the role of full-duplex radio for securing wireless network from a new
perspective. It first studies the secrecy capacity of two single-antenna full-duplex users …

Physical layer security and full duplex have been two widely applied techniques in wireless
communications community, where the physical layer security can prevent eavesdropping …

Consider a two-way communication scenario where two single-antenna nodes, operating
under full-duplex mode, exchange information to one another through the aid of a (full …

In this article, we investigate a reconfigurable intelligent surface (RIS)-aided multiuser full-
duplex secure communication system with hardware impairments at transceivers and RIS …

In this paper, we study the benefits of full-duplex (FD) receiver jamming in enhancing the
physical-layer security of a two-tier decentralized wireless network with each tier deployed …

Physical layer security (PLS) technologies are expected to play an important role in the next-
generation wireless networks, by providing secure communication to protect critical and …

In this paper, we investigate the secrecy performance of the multiple-input multiple-output
(MIMO) wiretap channels in the presence of an active full-duplex eavesdropper with …

This paper investigates the application of full-duplex (FD) multi-antenna transceivers in
proactive eavesdropping systems. To this end, we jointly optimize the transmit and receive …

In this correspondence, we investigate the physical layer security issue with the assistance
of a reconfigurable intelligent surface (RIS). In particular, we consider the single-input and …

In this letter, we consider the physical-layer security (PLS) in full-duplex (FD) multiuser
multiple-input-multiple-output (MIMO) short-packet communications, where a base station …
