    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: There is disclosed in one example a computing apparatus, including: a hardware platform; a network interface to communicatively couple to a bus lacking native support for authentication; and an anomaly detection engine to operate on the hardware platform and configured to: receive a first data stream across a first time; symbolize and approximate the first data stream, including computing a first window sum; receive a second data stream across a second time substantially equal in length to the first time, the second data stream including data across the plurality of dimensions from the first data stream; symbolize and approximate the second data stream, including computing a second window sum; compute a difference between the first window sum and the second window sum; determine that difference exceeds a threshold and that the correlation across the plurality of dimensions is broken; and flag a potential anomaly.
