摘要： An authentication system includes an authentication unit that performs an authentication process between a first communication device and a second communication device when the first communication device and the second communication device communicate. The authentication unit performs the authentication process by transmitting authentication information from one of the first communication device and the second communication device to the other one, calculating the authentication information with an encryption code in each of the first communication device and the second communication device, and evaluating a calculation result. During a processing series in the authentication process, the authentication unit performs a first authentication based on part of the calculation result transmitted between the first and second communication device, and a second authentication based on another part of the calculation result transmitted between the first and second communication device.

摘要： A portable electronic key device starts up only when movement of the portable electronic key device is present on the basis of detection signal Sac of a motion detector. A communication monitoring unit monitors whether or not radio waves Swk periodically transmitted from a vehicle are received. When there is no movement of the portable electronic key device but the portable electronic key device has received or is receiving radio waves from the vehicle, an operation controller maintains the start-up state of the portable electronic key 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： This key information generation system generates key information necessary when using a shared device and imparts this key information to a mobile terminal. Authentication is performed between a mobile terminal which has imported key information, and an authentication device provided to the device, and if said authentication is successful, the mobile terminal enables operation of the device via the authentication device. The key information generation system includes: an information management unit which manages, by associating with one another, individual information for the authentication device, a key information generating code, and usage information pertaining to the use of the authentication device; and a key information generation unit which specifies a key information generation code from the individual information and usage information managed by being associated with one another by the information management unit, and generates key information on the basis of the key information generation code.
