摘要： A theft prevention system capable of preventing theft of a target object by disabling the authorized key of the target object in the case where the authorized key has been stolen. When the authorized key is lost, a mobile telephone instructs a vehicle control device to set a warning mode. On receipt of this warning mode instruction, the vehicle control device sets warning mode, generates an electronic key, and transmits the generated electronic key to the mobile telephone, which receives and stores the electronic key. Once the warning mode is set in the vehicle, locking and unlocking are only possible using the electronic key. If the authorized key is found, the mobile telephone instructs the vehicle control device to set the normal mode. Upon receipt of this normal mode instruction, the vehicle control device sets the normal mode in the vehicle.

摘要： A theft prevention system capable of preventing theft of a target object by disabling the authorized key of the target object in the case where the authorized key has been stolen. When the authorized key is lost, a mobile telephone 100 instructs a vehicle control device 300a to set a warning mode. On receipt of this warning mode instruction, the vehicle control device 300a sets warning mode, generates an electronic key, and transmits the generated electronic key to the mobile telephone 100, which receives and stores the electronic key. Once the warning mode is set in the vehicle, locking and unlocking are only possible using the electronic key. If the authorized key is found, the mobile telephone 100 instructs the vehicle control device 300a to set the normal mode. Upon receipt of this normal mode instruction, the vehicle control device 300a sets the normal mode in the vehicle. Once the normal mode is set in the vehicle, locking and unlocking are only possible using the authorized key.

摘要： The subkey data generating unit 101 has two different subkey key generation processes. When encrypting a (T*n)th plaintex block (where T denotes a predetermined cycle and n is a positive integer), sixteen sets of subkey data are generated. In all other cases, two sets of subkey data are generated. The encrypting unit 100 encrypts the plaintex using the generated sixteen or two sets of subkey data.

摘要： In an authentication system, a key registration apparatus receives input of an identifier unique to a second device, generates first key data from the identifier according to a predetermined key generation algorithm, and transmits the generated first key data to a first device, which receives and stores the first key data, and authenticates the second device with use of the first key data. The second device stores in advance second key data generated from the identifier according to the predetermined key generation algorithm, and is authenticated by the first device with use of the second key data. Accordingly, the first and second devices cannot be registered without using the key registration apparatus, thereby preventing communication with unregistered devices. This enables usage of content to be limited to individual usage in the home of a user, and can be realized even with devices that are not connected outside the home.
摘要翻译：在认证系统中，密钥注册装置接收对第二装置唯一的标识符的输入，根据预定的密钥生成算法从标识符生成第一密钥数据，并将生成的第一密钥数据发送到第一装置，存储第一密钥数据，并使用第一密钥数据认证第二设备。第二设备预先存储根据预定密钥生成算法从标识符生成的第二密钥数据，并且通过第二密钥数据由第一设备认证。因此，在不使用密钥登记装置的情况下，不能登记第一和第二装置，从而防止与未登记装置的通信。这使得内容的使用被限制在用户的家庭中的个人使用，并且即使使用不在家外的设备也可以实现。

摘要： An object of the present invention is to provide a technology to improve security against spoofing in a method of authentication using a challenge and response system.In the method of authentication of the present invention, the piece of challenge data is transmitted from the sever 10 to the terminal 20 (S104), and then the piece of response data, which is the decrypted challenge data (S105), is transmitted from the terminal to the server (S107). Further, whether the piece of response data is the piece of challenge data decrypted or not is judged based on encryption performed in the server 10 (S109). When the result of judgment is affirmative, the parameter used both for encryption and decryption is renewed to a parameter to be used in the next authentication (S111, S112).
