Robust and secure communications using dynamic rotations reconfigurable intelligent surface

This paper investigates the secure transmission problem using a dynamically reconfigurable intelligent surface (RIS). Considering an eavesdropping scenario where a multi-antenna eavesdropper has inadequate channel state information, a resilient beamforming strategy is proposed to simultaneously opti...
