    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: 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.

    摘要: A cryptographic processing apparatus for performing cryptographic processing using input data to generate output data is provided. The cryptographic processing apparatus includes a storage unit for storing chain data which is used for reflecting present cryptographic processing on next cryptographic processing, and for renewing the chain data each time cryptographic processing is performed, a merging unit for merging the chain data stored in the storage unit with the input data to generate merged data, and a main cryptographic processing unit for performing main cryptographic processing using the merged data to generate output data and for outputting intermediate data generated during a generation of the output data, wherein the storage unit renews the chain data by storing the intermediate data outputted by the main cryptographic processing unit as the new chain data, which is used for the next cryptographic processing.
