Abstract

A vehicle control system, including an in-vehicle bus and a plurality of electronic control units (ECUs) coupled to the in-vehicle bus, wherein at least one ECU of the plurality of ECUs is configured to: receive, at a respective at least one ECU of the plurality of ECUs, a message in a message stream on the in-vehicle bus; evaluate the message to determine at least one of a confidence value of the security classification, a significance value of the message, or a bounds check value of the message; and determine in real-time to allow or deny the message to the vehicle control system based on at least one of the significance value of the message, the bounds check value of the message, or the confidence value of the security classification of the message, to provide a sanitized message stream to the vehicle control system.
