    • An encryption/decryption device includes a storage section which stores input data and output data, a first encryption/decryption processing section which performs first encryption and decryption processing, and a second encryption/decryption processing section which performs second encryption and decryption processing. The encryption/decryption device stores decrypted data obtained by causing one of the first and second encryption/decryption processing sections to perform the first or second decryption processing for the input data in the storage section. The encryption/decryption device stores data obtained by causing the other of the first and second encryption/decryption processing sections to perform the first or second encryption processing for the decrypted data in the storage section as the output data. The storage area of the storage section for the decrypted data is configured to be inaccessible from the outside of the encryption/decryption device.
    • 加密/解密装置包括存储输入数据和输出数据的存储部分,执行第一加密和解密处理的第一加密/解密处理部分,以及执行第二加密和解密处理的第二加密/解密处理部分。 加密/解密装置存储通过使第一和第二加密/解密处理部中的一个对存储部中的输入数据执行第一或第二解密处理而获得的解密数据。 加密/解密装置存储通过使第一和第二加密/解密处理部分中的另一个对存储部分中的解密数据执行第一或第二加密处理而获得的数据作为输出数据。 用于解密数据的存储部分的存储区域被配置为从加密/解密设备的外部不可访问。

    • An encryption/decryption device includes an encryption/decryption processing section which performs encryption or decryption processing for divided data of first and second content data in an operation mode of a block cipher method using data in a block other than a block under processing, and an intermediate value storage section which stores a processing result or an input value of the encryption/decryption processing section in content units. After the processing result or the input value of the encryption/decryption processing section for one of the divided data of the second content data has been stored in the intermediate value storage section, the processing result or the input value for the Kth divided data of the first content data is read from the intermediate value storage section, and the encryption/decryption processing section performs the encryption or decryption processing for the (K+1)th divided data of the first content data by using the processing result or the input value.
    • 一种加密/解密装置包括:加密/解密处理部分,其使用在处理中的块以外的块中的数据的块密码方法的操作模式中对第一和第二内容数据的划分数据执行加密或解密处理, 中间值存储部,其以内容单位存储加密/解密处理部的处理结果或输入值。 在第二内容数据的划分数据之一的处理结果或加密/解密处理部分的输入值已被存储在中间值存储部分中之后,处理结果或第K个分割数据的输入值 从中间值存储部分读取第一内容数据,并且加密/解密处理部分通过使用处理结果或输入值来执行第一内容数据的第(K + 1)个划分数据的加密或解密处理。
