Abstract
A center device includes an update data storage unit in which new data and new difference data for updating to the new data from old data are stored for, among electronic control units mounted on a vehicle, a target device targeted for data update. The center device generates, using the new data, a first verification value for verifying integrity in the vehicle, and generates, using the new difference data, a second verification value for verifying integrity of the new difference data in the vehicle. The center device generates a package including the new difference data, the first verification values and the second verification values for a plurality of the target devices. The center device generates, using the distribution package, a third verification value for verifying integrity of the distribution package in the vehicle, and transmits the distribution package along with the third verification value to the in-vehicle device.
