Abstract: Techniques and screening messages based on tags in an automotive environment, such as, messages communicated via a communication bus, like the CAN bus. Messages can be tagged with either a binary or probabilistic tag indicating whether the message is fraudulent. ECUs coupled to the CAN bus can receive the messages and the message tags and can determine whether to fully consume the message based on the tag.

Abstract: Methods and apparatus relating to a physics-based approach for attack detection and/or localization in closed-loop controls for autonomous vehicles are described. In an embodiment, multiple state estimators are used to compute a set of residuals to detect, classify, and/or localize attacks. This allows for determination of an attacker's location and the kind of attack being perpetrated. Other embodiments are also disclosed and claimed.
