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 stores a shared key to be mutually shared with one or more ECUs. Each of the ECUs acquire a session key by communication with the master ECU 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 executes inspection of a security state of the shared key stored by the ECU or the like."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Key management method used in encryption processing for safely transmitting and receiving messages","description":"Provided is a key management method to secure security in an onboard network system having multiple electronic control units storing a shared key.
