  • Publication number: 20220355807
    Abstract: Systems, apparatus, methods, and techniques for an ego vehicle to respond to detecting misbehaving information from remote vehicles are provided. An ego vehicle, in addition to reporting misbehaving vehicles to a misbehavior authority via a vehicle-to-anything communication network, can, take additional actions based in part on how confident the ego vehicle is about the evidence of misbehavior. Where the confidence is high the ego vehicle can simply discard the misbehaving data and provide an alternative estimate for such data from alternative sources. Where the confidence is not high the ego vehicle can request assistance from neighboring vehicles and roadside units to provide independent estimates of the data to increase confidence in the evidence of misbehavior.

  • Publication number: 20220350888
    Abstract: Logic may implement observation layer intrusion detection systems (IDSs) to combine observations by intrusion detectors and/or other intrusion detection systems. Logic may monitor one or more control units at one or more observation layers of an in-vehicle network, each of the one or more control units to perform a vehicle function. Logic may combine observations of the one or more control units at the one or more observation layers. Logic may determine, based on a combination of the observations, that one or more of the observations represent an intrusion. Logic may determine, based at least on the observations, characteristics of an attack, and to pass the characteristics of the attack information to a forensic logging system to log the attack or pass the characteristics of the attack to a recovery system for informed selection of recovery procedures. Logic may dynamically adjust a threshold for detection of suspicious activity.

  • Patent number: 11463262
    Abstract: Various embodiments are generally directed to providing authentication and confidentiality mechanisms for message communication over an in-vehicle network. For example, authentication data associated with a communicating node may be transmitted over the network by encoding different predefined voltage levels on top of the message bits of the message being communicated. Different voltage levels may represent different encodings, such as a bit-pair or any bit combination of the authentication data. In a further example, messaging confidentiality between at least two communicating nodes may be achieved by pseudo-randomly flipping, or scrambling, the dominant and recessive voltages of the entire message frame at the analog level based on a pseudo-random control bit sequence.
