In this paper, we investigate the robust and secure transmission for a reconfigurable intelligent surface (RIS) assisted multi-user simultaneous wireless information and power transfer (MU-SWIPT) system in the presence of an eavesdropper (Eve) with hardware impairments (HWIs). An optimization proble...
