Abstract
Described is a system for side-channel based detection of cyber-attack. In operation, the system converts data bus signals from a platform (e.g., vehicular platform) into a first time series of system states. The system further converts analog side-channel signals from the platform into a second time-series of system states. Anomalous behavior of the platform is detected by comparing the first time series of system states with the second time series of system states to identify violations of predetermined constraints. Upon detection, the anomalous behavior is designated as a cyber-attack of the platform, which causes the platform to initiate an action based on the detected cyber-attack. Such actions include implementing a safe made, etc.
