    Abstract: Systems, methods, computer-readable storage media, and apparatuses to provide active attack detection in autonomous vehicle networks. An apparatus may comprise a network interface and processing circuitry arranged to receive a first data frame from a first electronic control unit (ECU) via the network interface, determine a voltage fingerprint of the first data frame, compare the voltage fingerprint to a voltage feature of the first ECU, determine that the first data frame is an authentic message when the voltage fingerprint does match the voltage feature of the first ECU, and determine that the first data frame is a malicious message when the voltage fingerprint does not match the voltage feature of the first ECU. Other embodiments are described and claimed.

    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.

    Abstract: Various systems and methods for bus-off attack detection are described herein. An electronic device for bus-off attack detection and prevention includes bus-off prevention circuitry coupled to a protected node on a bus, the bus-off prevention circuitry to: detect a transmitted message from the protected node to the bus; detect a bit mismatch of the transmitted message on the bus; suspend further transmissions from the protected node while the bus is analyzed; determine whether the bit mismatch represents a bus fault or an active attack against the protected node; and signal the protected node indicating whether a fault has occurred.

    Abstract: Techniques for clock manager monitoring for time sensitive networks are described. An apparatus, comprises a clock circuitry to manage a clock for a device, a processing circuitry coupled to the clock circuitry, the processing circuitry to execute instructions to perform operations for a clock manager, the clock manager to receive messages with time information for a network and generate clock manager control information to adjust the clock to a network time for the network, and a detector coupled to the processing circuitry and the clock circuitry, the detector to receive the clock manager control information, generate model control information based on a clock model, compare the clock manager control information with the model control information to generate difference information, and determine whether to generate an alert based on the difference information. Other embodiments are described and claimed.
