Abstract
A system for cyber-attack detection within cyber-physical systems (such as a vehicle). The system operates by obtaining a time-varying analog side-channel signal from components with the cyber-physical system and converting the time-varying analog side-channel signal to a digital side-channel signal. A time-series of system states are then identified based on the digital side-channel signal. The time-series of system states are compared with software states as generated by the cyber-physical system components, such that when the software states are unmatched with the time-series of system states, a side-channel is designated as having a security breach. In such an event, the cyber-physical system is then caused to implement an action based on the side-channel security breach.
