    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: A personal information management device aims to save troubles of inputting passwords and deleting personal information, to prevent others from viewing the personal information, and to maintain confidentiality of the personal information even when a mobile device is lost. Personal information storage unit 201 holds encrypted personal information, key distribution unit 204 distributes a decryption key used for decrypting the encrypted personal information into a first and a second distributed keys based on a secret sharing scheme, distributed key storage unit 205 stores thereon the first distributed key, stores the second distributed key on home device 30, and deletes the decryption key. Upon decryption, link judgment unit 210 judges link establishment. Key recovery unit 207 acquires the second distributed key from home device 30, and recovers the decryption key using the first and the second distributed keys. Decryption unit 208 decrypts the encrypted personal information using the decryption key.

    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: In an exponentiation device, a relatively large table is generated outside of a coprocessor so as to enable high-speed exponentiation to be performed using the small window method. The selection of data from the table and transfer of data to the coprocessor are conducted in parallel with a multiple-length arithmetic operation performed in the coprocessor. So as to avoid bottlenecks occurring in the data transfer between a CPU and the coprocessor, two data banks are provided in the coprocessor for storing the data to be used in the arithmetic operation. By providing two banks in the coprocessor, it is possible to use one for transferring data while data stored in the other is being used in the arithmetic operation. When the operation using the stored data has been completed, the banks are switched, and the arithmetic operation is then repeated using the newly transferred data while at the same time conducting data transfer in readiness for the following operation.

    摘要: An RSA decryption apparatus that is used in an IC card or the like counters a differential fault attack. The RSA decryption apparatus computes at high speed a public key used in data verification, without having to obtain the public key from an external source. The RSA decryption apparatus includes a remainder computation unit 412 that calculates dp=d mod (p−1), and an inverse computation unit 414 that finds an inverse of dp over a residue field with p−1 as a modulus. The RSA decryption apparatus verifies a decipher text with use of the inverse of dp as the public key. The reduced bit count in inverse computation compared to if the inverse of d is found as the public key increases computing speed.
