Aspect-oriented Modeling of Attacks in Automotive Cyber-Physical Systems

by Armin Wasicek

This paper introduces aspect-oriented modeling (AOM) as a powerful, model-based design technique to assess the security of Cyber-Physical Systems (CPS). Particularly in safety- critical CPS such as automotive control systems, the protection against malicious design and interaction faults is paramount to guaranteeing correctness and reliable operation. Essentially, attack models are associated with the CPS in an aspect-oriented manner to evaluate the system under attack. This modeling technique requires minimal changes to the model of the CPS. Using application-specific metrics, the designer can gain insights into the behavior of the CPS under attack.

Recognizing Manipulated Control Units

by Armin Wasicek

Combatting the modification of automotive control systems is a current and future challenge for OEMs and suppliers. ‘Chip- tuning’ is a manifestation of manipulation of a vehicle’s original setup and calibration. This talk presents a learning system called a recognition module that continuously monitors vehicle’s sensor data and compares that data to a reference model consisting of a set of classifiers that have been trained on the intended behavior of a control unit. When the vehicle is on the road, the recognition module uses these classifiers to ascertain that the behavior of the vehicle is as intended.
