Transmitter Actions for Secure Integrated Sensing and Communication
, Linköping UniversityAbstract
This work models a secure integrated sensing and communication (ISAC) system as a broadcast channel with action-dependent channel states and output feedback. The transmitted message is split into a common and a secure message, both of which must be recovered at the legitimate receiver, while the secure message needs to be kept secret from the eavesdropper. The transmitter actions, such as beamforming vector design, affect the corresponding state distribution at each channel use. The action sequence is modeled to depend on both the transmitted message and channel output feedback. For perfect channel output feedback, the secrecy-distortion regions are provided for physically-degraded and reversely-physically-degraded secure ISAC channels with transmitter actions. The corresponding rate regions when the entire message should be kept secret are also provided. We illustrate the results by characterizing the secrecy-distortion region of a binary example.
