The general ECU attaches a digital signature to transmission data including data (for example, a digest value of a program) and transmits the transmission data to the master ECU. The master ECU verifies the digital signature and the data and, when both the digital signature and the data are valid, determines that the general ECU is valid. The master ECU attaches a digital signature to transmission data including data of the master ECU and a session key and transmits the transmission data to the general ECU. The general ECU verifies the digital signature and the data and, when both the digital signature and the data are valid, the general ECU uses the session key included in the transmission data as a common key when performing subsequent communications."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle system and authentication method","description":"A vehicle system includes a master ECU and a general ECU.
