Enhancing Physical Layer Security With RIS Under Multi-Antenna Eavesdroppers and Spatially Correlated Channel Uncertainties

Reconfigurable intelligent surface (RIS) has the capability to significantly enhance physical layer security by reconfiguring the propagation in wireless communications. However, due to the cascaded channel brought by the RIS and the hostile nature of potential eavesdroppers, acquiring perfect chann...
