Abstract
Systems and methods for performing vehicle software attestation. One system includes an electronic control unit (ECU) master included in a vehicle and a verifier system. The ECU master receives a digital shadow request generated by the verifier system and generates a digital shadow. The digital shadow is based on a unique, one-way identifier of a program memory space of the ECU master and a unique, one-way identifier of a program memory space of each of a plurality of other ECUs included in the vehicle. The ECU master transmits the digital shadow to the verifier system. The verifier system receives the digital shadow from the ECU master as a first digital shadow, receives a second digital shadow from a digital twin representing software installed in the ECU master and each of the plurality of other ECUs, and determines whether the first digital shadow matches the second digital shadow.
