摘要： The content decrypting apparatus 2000 of the present invention stores a chaining value generated during decryption of the last ciphertext block of a chunk in association with a content type and a frame number to an inter-chunk chaining value holding unit 216. When decrypting the first ciphertext block of a chunk, and in case where a chaining value is stored to the inter-chunk chaining value holding unit 216 in association with a content type and a frame number corresponding to the chunk, the content decrypting apparatus decrypts the first ciphertext block of the chunk using the chaining value. Hence, the content decrypting apparatus pertaining to the present invention is capable of correctly decrypting data streams having a data structure in which ciphertext chunks belonging to a first encrypted frame are disposed in between two ciphertext chunks belonging to a second encrypted frame.

摘要： The present invention relates to a confidential information processing device, a confidential information processing apparatus, and a confidential information processing method, and particularly to a confidential information processing device which performs multiple cryptographic computation for different target data included in a data stream. With this configuration, the context control unit outputs the stream on which the cryptographic computation is performed to an external device or other stream analysis unit. Thus, by setting the number of cryptographic computation on a correspondence table, the number of computation can be set to any number. Thus, the confidential information processing device according to the present invention can perform any number of cryptographic computations on one stream. Furthermore, without outputting the stream whenever a cryptographic computation is completed, multiple cryptographic computations can be performed with one stream input. In addition, by setting the number of cryptographic computation on the correspondence table, the number of computation can be easily changed.
摘要翻译：机密信息处理装置，机密信息处理装置以及机密信息处理方法技术领域本发明涉及机密信息处理装置，机密信息处理装置以及机密信息处理方法，特别涉及对包含在数据流中的不同目标数据进行多次密码计算的机密信息处理装置。利用该配置，上下文控制单元将执行了加密计算的流输出到外部设备或其他流分析单元。因此，通过在对应表上设定密码计算的次数，可以将计算次数设定为任意个数。因此，根据本发明的机密信息处理装置可以在一个流上执行任何数量的密码计算。此外，每当加密计算完成时，不输出流，可以用一个流输入来执行多个密码计算。另外，通过在对应表上设定密码计算的次数，可以容易地改变计算次数。
