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: Time recovery techniques are described. A method comprises receiving messages from the first device by the second device in the first network domain, the messages to comprise time information to synchronize a first clock for the first device and a second clock for the second device to a network time, determining the second clock is to recover the network time for the second device without new messages from the first device, retrieving a first set of timestamps previously stored for events in the first network domain using the network time from the second clock, retrieving a second set of timestamps previously stored for the events in the first network domain using a redundant time from a third clock, where the third clock is not synchronized with the first and second clocks, and recovering the network time using a regression model and the redundant time from the third clock.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for anomaly detection and recovery. An apparatus to isolate a first controller in an autonomous vehicle includes a first controller to control a reference signal of the autonomous vehicle via a communication bus, a second controller to control the reference signal of the autonomous vehicle when the first controller is compromised, and a message neutralizer to neutralize messages transmitted by the first controller when the first controller is compromised, the neutralized messages to cause the first controller to become isolated from the communication bus.

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 transitions associated with the transmission at a point on the in-vehicle network bus. A domain bitmap can be generated from the observed voltage transitions. ECUs can be identified and/or fingerprinted based on the domain bitmaps.

Abstract: Systems, apparatuses, and methods to attest to and verify the integrity of cargo during transport by an autonomous vehicle are provided. An autonomous vehicle can discretize parameters associated with transportation of cargo and can generate a keyed hash digest from the discretized parameters. The keyed hash digest can be sent to a stakeholder in the transportation of the cargo to attest to the integrity of the cargo during transport.
