    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, code, 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 arranged in a communication subject communicable with an electronic key. A registration tool is in wired or wireless connection with the communication subject. The registration tool registers the electronic key to the controller when receiving a registration permission signal. An information center is connected to a network. The registration tool includes an operator ID acquisition unit that acquires an operator ID from a key registration operator. A communication unit sends the operator ID to the information center through the network. The information center includes an operator ID verification unit that verifies the operator ID received from the registration tool. A permission information notification unit sends, when the operator ID is verified, a registration permission signal to the registration tool through the network to permit the registration tool to perform the registration process.

    摘要： An electronic key system determines that legitimate communication has been performed on the basis of conditions including that a measured distance from a ranging request unit to a ranging response unit measured on the basis of a ranging request signal and a ranging response signal is within a threshold range that is set on the basis of the distance from a communication area of a transmission antenna where an electronic key is determined to be located by a key location determination unit to one of either the ranging request unit or the ranging response unit that is provided in an on-board device.

    摘要： A car sharing system includes a car sharing device installed in a vehicle. The car sharing device is configured to perform ID verification via an electronic key system of the vehicle in a state in which key information registered to the mobile terminal has been authenticated to allow an onboard device to be operated by the mobile terminal. The car sharing system includes a key function unit that implements a smart function to perform the ID verification through bidirectional short-range wireless communication with the electronic key system, a determination processing unit that determines whether or not a condition for permitting actuation of the smart function has been satisfied, and an actuation switching unit that validates the smart function if the condition for permitting actuation of the smart function has been satisfied.

    摘要： A method for registering an electronic key to a controller of a communication subject includes locating an electronic key ID of a registered electronic key, which is registered to a first controller that was previously installed in the communication subject, based on a communication subject ID unique to the communication subject, and reregistering the registered electronic key to a second controller installed in the communication subject in lieu of the first controller by storing the electronic key ID of the registered electronic key and an encryption code corresponding to the electronic key ID in the second controller.

    摘要： An immobilizer ECU transmits a vehicle ID code and a SEED code, which is read from an electronic key, to a data center online. The data center generates an encryption key from the received SEED code and a first logic, and generates a further SEED code from the encryption key, the vehicle ID code, and a second logic. The immobilizer ECU obtains the further SEED code online from the data center, generates the encryption key from the obtained further SEED code, the vehicle ID code, and the second logic, and stores the encryption key.
