Abstract

This paper considers an information theoretic model of secure integrated sensing and communication, represented as a wiretap channel with action dependent states. This model allows securing part of a transmitted message against a sensed target that eavesdrops the communication, while enabling transmitter actions to change the channel statistics. An exact secrecy-distortion region is given for a physically-degraded channel. A finite-length achievability region is established for the model using an output statistics of random binning method, giving an achievable bound for low-latency applications.
