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 …

Eavesdropping and jamming pose great threats to the security of wireless communication. In
this paper, a secure multicast communication system of transmitting different messages to a …

Joint active and passive beamforming optimization is investigated to enhance the physical
layer security of a reconfigurable intelligent surface (RIS)-assisted multiple-antenna …

Reconfigurable intelligent surfaces (RISs) are recognized with great potential to strengthen
wireless security, yet the performance gain largely depends on the deployment location of …

Intelligent reconfigurable surface (IRS) is an innovative and promising technology to achieve
intelligent reconfigurable wireless environment, and thus, enables cost-effective and energy …

Wireless communications are increasingly vulnerable to simultaneous jamming and
eavesdropping attacks due to the inherent broadcast nature of wireless channels. With this …

In this paper, we investigate the physical layer security of a full-duplex base station (BS)-
aided system in the worst case, where an uplink transmitter (UT) and a downlink receiver …

The reconfigurable intelligent surface (RIS) is envisioned to create ultra-secure wireless
networks. Previous works on the RIS-assisted security provisioning techniques assumed …

The communication messages carried by the detected waveforms in integrated sensing and
communication (ISAC) will be at risk of being eavesdropped by the detected targets, which …

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 …
