Abstract: In a ledger execution unit of a distributed ledger system, a node communicates with a provider terminal to thereby execute a transaction, and a node communicates with a user terminal to thereby execute a transaction. A storage unit is configured in such a way that at least one of the nodes generates a new distributed information item indicative of a record of the transactions, and each of the nodes stores the new distributed information item.

Abstract: A center device is provided that manages data to be written to electronic control units mounted on a vehicle. The center device includes an update data storage unit that stores update data for a data update target device among the electronic control units. The center device distributes the update data to the vehicle. The center device includes an individual vehicle configuration information storage unit that stores identification information of target vehicles targeted for update using the update data, and update status information regarding update completion status and update-in-progress status acquired as update status from target vehicles. The center device manages the update status information of the target vehicles in a statistically tabulatable manner on basis of the update status information.

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.

Abstract: A ledger management system includes multiple ledger management devices communicably connected to each other. The ledger management devices have a same distributed ledger. Each ledger management device includes the distributed ledger, an agreement determination unit, and a ledger storage unit. The distributed ledger stores ledger information, including specific information specific to a previous ledger information and present vehicle information obtained from a vehicle, that is generated by one of the ledger management devices. The agreement determination unit determines whether the ledger information generated by the one of the ledger management devices satisfies an agreement rule. The ledger storage unit stores the ledger information in the distributed ledger when the ledger information satisfies the agreement rule, and does not store the ledger information in the distributed ledger when the ledger information does not satisfy the agreement rule.
