Secure Integrated Sensing and Communication

This work considers the problem of mitigating information leakage between communication and sensing in systems jointly performing both operations. Specifically, a discrete memoryless state-dependent broadcast channel model is studied which (i) presence feedback enables transmitter to convey information, while simultaneously state estimation; one receivers treated as an eavesdropper whose should be estimated but remain oblivious part transmitted information. The abstracts challenges behind security for joint if views key attribute, e.g., location. For independent identically distributed states, perfect output feedback, when message kept secret, partial characterization secrecy-distortion region developed. exact either physically-degraded or reversely-physically-degraded. also extended situation entire secret. benefits approach compared separation-based secure state-sensing methods are illustrated with binary models.
