A secure integrated sensing and communication (ISAC) system enhanced by an active reconfigurable intelligent surface (RIS) is investigated in the letter. Unlike existing works, the proposed fairness-aware beamforming framework jointly ensures fair multi-target detection and secure multi-user communi...
