摘要： A car sharing system includes a car share device and a communication control unit. The car share device is configured to perform wireless communication with a mobile terminal that is operable as an electronic key. The communication control unit controls the wireless communication between the mobile terminal and the car share device so that an authentication process through bidirectional communication is executed only when a communication connection establishment process is performed. After the wireless communication has been established, the communication control unit controls the wireless communication so that actuation of an on-board device is permitted in accordance with operation of the mobile terminal through unidirectional communication from the mobile terminal to the car share device.

摘要： An electronic key registration system includes an electronic key and a communication master. The electronic key transmits a registration code. The communication master receives the registration code from the electronic key, obtains key information using the registration code, and registers the key information. The registration code is set in accordance with the communication master to which the electronic key is registered. The communication master includes a level determination unit, which determines a key registration security level when the electronic key is registered to the communication master, and a registration execution unit, which obtains the key information using the registration code based on the determined key registration security level and registers the key information to the communication master.

摘要： An electronic key registration system includes a controller of a communication subject, an initial electronic key that communicates with the communication subject and has an initial encryption key generation code, an additional electronic key that communicates with the communication subject, and an information center including an additional encryption key. The initial electronic key holds an initial encryption key generated from the initial encryption key generation code and a logic. The controller holds the logic and identification information of the communication subject. The controller acquires the initial encryption key generation code from the initial electronic key, generates an initial encryption key from the initial encryption key generation code and the logic held by the controller, and stores the initial encryption key. The information center sends the additional encryption key to the additional electronic key or the controller through a network.
