摘要： The present invention provides a smart meter for use in automatic meter reading of power, gas, and the like, preventing falsification of a program and data and assuring security in a communication path. A smart meter has: a data processor receiving a measurement signal according to a use amount, computing meter read data, and performing communication control by a communication unit coupled to a network; and a secure processor having tamper resistance for internally held information and performing secure authenticating process for a remote access. The data processor encrypts computed meter read data with a public key unique to the smart meter and supplies the encrypted data to the secure processor. The secure processor decrypts the encrypted meter read data with the secret key unique to the smart meter and stores the decrypted or encrypted meter read data into a nonvolatile storage region.

摘要： An electric vehicle information system prevents circulation of non-authentic batteries and battery components for electric vehicles. An electric vehicle data processing system is employed that performs, on an electric vehicle battery module having a plurality of battery cells installed therein, authentication of individual battery cells and the battery module itself in a hierarchical manner using a microcomputer. An electric vehicle is configured so as to cause the microcomputer of the data processing system to accumulate voltage history and charge history of the batteries in a nonvolatile storage circuit. The history information and the electric vehicle ID can be gathered by a maintenance device and a data server via an electronic control unit of the electric vehicle. A maintenance service system may thus be provided.
