Abstract: Techniques include receiving a message with time information from a clock leader by a clock follower in a time-synchronized network (TSN), the time information to synchronize a clock to a network time for the TSN, retrieving an actual time offset value for the message, the actual time offset value to comprise a value between an actual sending time and an actual receiving time of the message, retrieving an estimated time offset value for the message, the estimated time offset value to comprise a value between an estimated sending time and an estimated receiving time of the message, the estimated time offset value generated using a physics-aware model of the TSN and a clock adjustment value for the clock based on the time information, and determining whether the time information for the message was modified to cause the clock to desynchronize based on difference information. Other embodiments are described and claimed.

Abstract: A data processing system includes technology for detecting and tolerating faults. The data processing system comprises an electronic control unit (ECU) with a processing core and a fault-tolerant elliptic curve digital signature algorithm (ECDSA) engine. The fault-tolerant ECDSA engine comprises multiple verification state machines (VSMs). The data processing system also comprises nonvolatile storage in communication with the processing core and ECU software in the nonvolatile storage. The ECU software, when executed, enables the data processing system to operate as a node in a distributed data processing system, including receiving digitally signed messages from other nodes in the distributed data processing system. The ECU further comprises a known-answer built-in self-test unit (KA-BISTU). Also, the ECU software comprises fault-tolerant ECDSA engine (FTEE) management software which, when executed by the processing core, utilizes the KA-BISTU to periodically test the fault-tolerant ECDSA engine for faults. 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, apparatuses, and methods to establish a mapping between message identifications for messages transmitted on a communication bus and electronic control units transmitting the messages is provided. In particular, retransmission of a low priority message onto the bus is forced such that the retransmitted low priority message overlaps with a higher priority message to determine whether the messages originated from the same ECU.

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.
