SECURE COMMUNICATION BETWEEN VEHICLE COMPONENTS VIA BUS GUARDIANS

Abstract:

In one embodiment, a computing system of an autonomous vehicle may receive a first set of data packets on one or more networks. The computing system may analyze the data packets to determine, for each packet, one or more of an authenticity, a validity, or a correctness of the data packet. The computing system may perform a first action for the first set of data packets based on the analysis. The first action may include signaling a safety driver of the autonomous vehicle to take over manual control of the vehicle in response to the data packets failing to satisfy the one or more of the authenticity, the validity, or the correctness criteria.
