要約(英語): To realize connected and/or self-driving vehicles for a mobility environment, it requires an authentication mechanism to prevent spoofing of on-board units of the vehicle and a mechanism to prevent eavesdropping and tampering of communication data between an on-board unit and servers in the cloud. Considering the huge number of vehicles in the system, an authentication method is required to mitigate the complexity of operation and management for the number of vehicles. In this paper, we propose a data utilization system that securely stores in-vehicle LAN data, which consist of control data flowing inside a vehicle, in the cloud in real time, and provides this information securely to third parties such as vehicle users, car dealers, and non-life insurance companies. The system uses ID-based cryptography as a mutual authentication method between on-board units and the data collection servers, and uses a key generated from the ID of an on-board unit to ease the key management. We integrate the management information of the vehicle and the authentication key of the vehicle in the system, and thus reduces the complexity of the operation and the key management.
