Zusammenfassung:An in-vehicle authentication system has a vehicle communication apparatus (100) that is provided in a vehicle equipped with a plurality of ECUs and that communicates with each ECU of the plurality of ECUs. An authentication part (101) performs configuration authentication for authenticating validity of a configuration for each ECU, and registers an ECU that has failed the configuration authentication in an authentication error list. A determination part (102) determines an in-vehicle function that is realizable in the vehicle based on the authentication error list and a function correlation table which indicates correlation between an in-vehicle function realized in the vehicle and an ECU used to realize the in-vehicle function. A display part (107) displays the in-vehicle function determined to be realizable in the vehicle by the determination part (102) on a display (805).
