Abstract: A head unit (100) that is a vehicle communication apparatus connected to a bus in an in-vehicle network system, the in-vehicle network system including a plurality of apparatuses that perform communication of frames via the bus, includes a multimedia control unit (150) that identifies a transmit frame, the transmit frame being a frame to be delivered to the bus, and a system control unit (110) capable of exchanging information on frames with the multimedia control unit (150) via wired communication or wireless communication. At least one of the multimedia control unit (150) and the system control unit (110) determines a conformity of the transmit frame with a rule.

Abstract: Provided is a key management method to secure security in an onboard network system having multiple electronic control units storing a shared key. In the key management method of the onboard network system including multiple electronic units (ECUs) that perform communication by frames via a bus, a master ECU (400) stores a shared key to be mutually shared with one or more ECUs (100a through 100d). Each of the ECUs (100a through 100d) acquire a session key by communication with the master ECU (400) based on the stored shared key, and after this acquisition, executes encryption processing regarding a frame transmitted or received via the bus, using this session key. In a case where a vehicle in which the onboard network system is installed is in a particular state, the master ECU (400) executes inspection (e.g., steps S1201, S1203) of a security state of the shared key stored by the ECU (100a) or the like.
