    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: In an information input/output system, a user device inputs and outputs information to and from external sources including a key management device. The system includes the key management device that securely outputs invalid-device information specifying an invalid device unit that has been made invalid for use, and the user device that includes an input/output unit and a host unit. Via the input/output unit, input and output of information is enabled between the host unit and the external sources. The host unit securely receives, via the input/output unit, the invalid-device information outputted by the key management device and judges whether or not the input/output unit is an invalid device unit by referring to the received invalid-device information. When judging, that the input/output unit is an invalid device, the host unit thereafter prohibits input and output via the input/output unit. Due to this construction, the host unit can correctly judge whether or not the input/output unit is an invalid device unit.

    摘要: An authentication system is provided having a revocation list generation apparatus that constructs and stores a revocation list in a tree structure, the revocation list generation apparatus being used in combination with a revocation judgment apparatus. The authentication system improves upon conventional authentication systems because the memory capacity to store a Certificate Revocation List (CRL) in order to identify revoked certificates is reduced. The tree structure corresponds to public key certificate, which are identified by leaf identifies, and nodes from a leaf that corresponds to a revoked public key certificate.

    摘要: In a system composed of a recording apparatus that records digitized content such as a movie, or a reproduction apparatus that reproduces the digitized content, and a recording medium, a media key for use in recording or reproduction is encrypted by a plurality of device keys and recorded on the recording medium. Here, the recording apparatus or the reproduction apparatus specifies the encrypted media key that it is to decrypt, from amongst the plurality of encrypted media keys. A key management apparatus records node revocation patterns assigned to nodes in a tree structure to the recording medium in a particular order, as header information of key information, together with the encrypted media keys. The recording apparatus or the reproduction apparatus specifies the encrypted media key to be decrypted, by analyzing the node revocation patterns sequentially.

    摘要: A copyright protection system includes a recording device and a reproduction device. The recording device writes encrypted content, an encrypted content key for decrypting the encrypted content, and license information on a recording medium on which a unique media number has been recorded in an unrewritable state. The license information is generated using both the media number and the encrypted content key, and therefore reflects both values. The reproduction device reads the media number, the encrypted content key, and the license information from the recording medium, and judges whether the license information reflects both the media number and the encrypted content key. The reproduction device decrypts the encrypted content key, and decrypts the encrypted content using the content key only if the license information reflects both values. Thus, the copyright protection system allows only original recording media to be reproduced, and prohibits reproduction of copy recording media.
