    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: The present invention offers a prime calculating apparatus for achieving prime calculation where producing identical primes is avoided by simple management techniques. The prime calculating apparatus stores a known prime q and management information unique in the use range of primes. The prime calculating apparatus reads the management information; generates random information R based on the read management information; reads prime q; calculates prime candidate N, according to N=2×random information R×prime q+1, using the read prime q and generated random information R; tests whether the calculated prime candidate N is a prime; and outputs the calculated prime candidate N as a prime when the primality of the calculated prime candidate N is determined. Herewith, the prime calculating apparatus is able to calculate prime candidates from unique management information while avoiding producing identical primes.

    摘要: The present invention is a content distribution system for distributing contents. The content distribution system (1) includes a key issuing center (11), a server (12), eight output apparatuses (13a) to (13h), and a communication path (10) that connects them to each other. Here, a pair of the key issuing center (11) and each of the output apparatuses (13a) to (13h) is previously given an individual key shared between them. For example, the key issuing center (11) shares an individual key IKa with the output apparatus (13a), an individual key IKb with the output apparatus (13b), and an individual key IKh with the output apparatus (13h).

    摘要: A game system is composed of a home game execution apparatus and a portable game execution apparatus. The home game execution apparatus generates image data suitable for the image quality of the home game execution apparatus and image data suitable for the image quality of the portable game apparatus, transmits the pieces of the image data as necessary, and writes a game program to a portable recording medium. The portable game execution apparatus executes the game recorded on the portable recording medium while displaying the portable image received over the network. As a result, each game execution apparatus is able to execute the same game while displaying image data of an image quality suitable for the particular game execution apparatus.
