This article studies secure communication in an Internet of Things (IoT) network, where the
confidential signal is sent by an active refracting reconfigurable intelligent surface (RIS) …

In this paper, an active RIS assisted multiple-input single-output system is studied, and we
focus on enhancing the achievable secrecy rate of legitimate user in the presence of an …

In this paper, we investigate the physical layer security in the reconfigurable intelligent
surface (RIS)-aided cell-free networks. A maximum weighted sum secrecy rate problem is …

In practice, residual transceiver hardware impairments inevitably lead to distortion noise
which causes the performance loss. In this letter, we study the robust transmission design for …

A reconfigurable intelligent reflective surface (RIS)-assisted cognitive radio (CR) multiple-
input multiple-output (MIMO) secure communication system is considered. In the presence of …

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 a robust secrecy transmission scheme for intelligent reflecting
surface (IRS) aided communication systems. Different from all the existing works where IRS …

This paper investigates the robust beamforming design in a secrecy multiple-input single-
output (MISO) network aided by the intelligent reflecting surface (IRS) with simultaneous …

The secure transmission of the simultaneously transmitting and reflecting reconfigurable
intelligent surface (STAR-RIS) aided communication system is investigated. Considering the …
