Abstract:
A vehicle network system employing a controller area network protocol includes a bus, a first electronic control unit, and a second electronic control unit. The first electronic control unit transmits, via the bus, at least one data frame including an identifier relating to data used for a calculation for obtaining a message authentication code indicating authenticity of transmission content. The second electronic control unit receives the at least one data frame transmitted vis the bus and verifies the message authentication code in accordance with the identifier included in the at least one data frame.
