Abstract: A center device includes a vehicle information storage unit, a hash value generation unit, and a package generation unit. The vehicle information storage unit stores identification information for electronic control devices mounted in a vehicle and information of software architecture of the electronic control devices together with a type of the vehicle. The hash value generation unit is configured to generate difference data, calculate a hash value of the difference data, and store the calculated hash value in a hash value storage unit, for each electronic control device that is an update target. The package generation unit is configured to generate distribution package for the update target using corresponding hash value stored in the hash value storage unit.
