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: Systems, apparatus, methods, and techniques for reporting an attack or intrusion into an in-vehicle network are provided. The attack can be broadcast to connected vehicles over a vehicle-to-vehicle network. The broadcast can include an indication of a sub-system involved in the attack and can include a request for assistance in recovering from the attack. Connected vehicles can broadcast responses over the vehicle-to-vehicle network. The responses can include indications of data related to the compromised sub-system. The vehicle can receive the responses and can use the responses to recover from the attack, such as, estimate data.

Abstract: 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 signals associated with the transmission at a point on the in-vehicle network bus. A distribution can be generated from densities of the voltage signals. ECUs can be identified and/or fingerprinted based on the distributions.

Abstract: Apparatuses, methods and storage medium associated with same hand user authentication are disclosed herein. In embodiments, an apparatus, wearable on a user's wrist, may include a user authentication module to authenticate and grant access to the user. To authenticate the user, the user authentication module may be configured to receive sensor data indicative of movements of one or more fingers over a virtual grid, analyze the sensor data to determine the movements, and authenticate and grant the user access or deny the user access to the apparatus based at least in part on a result of the analysis. The one or more fingers are fingers of a hand of the user that adjoins the wrist on which the apparatus is worn. In embodiments, the senor data may include sensor data collected by sensors configured to measure tendon/muscle positions of the wrist. Other embodiments may be disclosed or claimed.
