摘要

We propose using the analog emissions of physical instrumentation (e.g., actuators, sensors, and mechanical structures) in a cyber-physical system (CPS) to send or leak information without impacting the CPS process characteristics. We show that one can use the analog emissions as covert channels to send information to a remote receiver without altering the functioning of the CPS by considering the...
