  • Patent number: 11553346
    Abstract: A first roadway system receives a communication from a second roadway system over a wireless channel, where the communication includes a description of a physical object within a driving environment. Characteristics of the physical object are determined based on sensors of the first roadway system. The communication is determined to contain an anomaly based on a comparison of the description of the physical object with the characteristics determined based on the sensors of the first roadway system. Misbehavior data is generated to describe the anomaly. A remedial action is initiated based on the anomaly.

  • Publication number: 20220393878
    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.

  • 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: 11490249
    Abstract: Systems and techniques for securing vehicle privacy in a driving infrastructure are described herein. A vehicle may contact a group identification (ID) issuer to register itself. A group ID may be received from the group ID issuer to indicate acceptance as a member. The vehicle may then contact the driving infrastructure to attach to the driving infrastructure using the group ID to identify the vehicle. In response, the vehicle receives an attachment ID from the driving infrastructure. Here, the attachment ID is used to secure communications between the vehicle and the driving infrastructure.

  • Publication number: 20220174479
    Abstract: Various embodiments are generally directed to techniques for providing improved privacy protection against vehicle tracking for connected vehicles of a vehicular network. For example, at least one road side unit may: identify a set of vehicles that require pseudonym changes and send an invitation for a pseudonym change event to each of the vehicles, determine at least a total number of the acceptances, determine whether the total number meets or exceeds a predetermined threshold number, send acknowledgement messages to the accepting vehicles if the threshold number is met, and form a vehicle group to coordinate the pseudonym change event during a privacy period. During the privacy period, the RSU and the vehicles may communicate with each other in a confidential and private manner via key-session-based unicast transmission, and coordinate transmission power and vehicle trajectory adjustments to maximize the benefits for safety and obfuscation for privacy.
