Reconfigurable Intelligent Surface (RIS) Exploitation in Integrated Sensing and Communication (ISAC) Multi-User MIMO Networks: Boosting and Degrading Sensing Performance

The paper explores both the beneficial and malicious potential of a reconfigurable intelligent surface (RIS) in an integrated sensing and communication (ISAC) multi-user MIMO network. The RIS can be leveraged to maximize the sensing signal-to-noise ratio (SNR) under communication user SINR constraints, but can also be exploited by a hacker to minimize the sensing SNR while preserving the communication performance.
