    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 encryption device encrypts a message, and includes a function value output unit that calculates a function value of the message using a one-way converting function. The encryption device also includes a numerical array output unit having an initial array decision unit that generates an initial decision array V1 having n1 elements of 1, n2 elements of −1, and (n−n1−n2) elements of 0. Further, the numerical array output unit includes an array element replacement unit that changes the array element of the initial array V1 generated by the initial array decision unit according to an input integer X, and outputs the array V. The encryption device also includes a text generation unit that generates encrypted text, based on the message, according to a polynomial which corresponds to the array V.

    摘要： A game system in which game software produced to be used in stationary game machines can be used in portable game machines. The game system includes a stationary game machine, a portable game machine, and a memory card connectable to both the stationary and portable game machines. Image data contained in game software produced for the stationary game machine shows an image in the form of free-form surface. The stationary game machine converts the image data to show the image in the form of a polygon according to processing performance of the portable game machine, and stores the converted image data and a game program executable by the portable game machine onto the memory card. The portable game machine executes the game program stored on the memory card, and generates and displays a display image from the image data stored on the memory card.
