Patent number: 11552963Abstract: Systems, apparatuses, and methods to identify an electronic control unit transmitting a message on a communication bus, such as an in-vehicle network bus, are provided. ECUs transmit messages by manipulating voltage on conductive lines of the bus. Observation circuitry can observe voltage transitions associated with the transmission at multiple points on the in-vehicle network bus. A voltage waveform can be generated from the observed voltage transitions. ECUs can be identified and/or fingerprinted based on the generated waveforms.Type: GrantFiled: December 19, 2019Date of Patent: January 10, 2023Assignee: Intel CorporationInventors: Shabbir Ahmed, Marcio Juliato, Christopher Gutierrez, Manoj Sastry, Liuyang Yang, Xiruo Liu

Publication number: 20220393878Abstract: 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.Type: ApplicationFiled: July 19, 2022Publication date: December 8, 2022Applicant: Intel CorporationInventors: MARCIO JULIATO, SHABBIR AHMED, CHRISTOPHER GUTIERREZ, XIRUO LIU, MANOJ SASTRY, LIUYANG YANG

Publication number: 20220355807Abstract: 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.Type: ApplicationFiled: July 6, 2022Publication date: November 10, 2022Applicant: Intel CorporationInventors: Xiruo Liu, Liuyang Yang, Manoj Sastry, Marcio Juliato, Shabbir Ahmed, Christopher Gutierrez

Publication number: 20220174479Abstract: 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.Type: ApplicationFiled: December 10, 2021Publication date: June 2, 2022Applicant: INTEL CORPORATIONInventors: Xiruo LIU, Shabbir AHMED, Ralf GRAEFE, Christopher GUTIERREZ, Marcio JULIATO, Rafael ROSALES, Manoj SASTRY, Liuyang YANG
