    • PURPOSE: To provide an information recording and reproducing device which can perform processing of a data analysis recording system and a data non- analysis recording system distinguishing clearly the both. CONSTITUTION: When an information recording mode is a data analysis recording system (Cognizant Mode) analyzing buried copy control information(CCI), a key for a data analysis recording system (Cognizant Mode) as a key for generating contents ciphering key in a data analysis recording system (Cognizant Key) is applied, when an information recording mode is a data non-analysis recording system (Non-Cognizant Mode) which does not analyze buried copy control information(CCI), a key for a data non-analysis recording system (Non- Cognizant Mode) is applied, a contents ciphering key is generated, and ciphering processing of contents is performed. Two data recording systems are performed being distinguished clearly by this constitution, the occurrence of mismatching of EMI being copy control information and buried CCI (Embedded CCI) is prevented.
    • 目的:提供可以进行数据分析记录系统和数据非分析记录系统的处理的信息记录和再现装置,以清楚地区分这两者。 规定:当信息记录模式是分析埋藏复制控制信息(CCI)的数据分析记录系统(认知模式)时,数据分析记录系统(认知模式)作为数据分析中生成内容加密密钥的关键 当信息记录模式是不分析埋藏复制控制信息(CCI)的数据非分析记录系统(非认知模式)时,记录系统(认知密钥)是数据非分析记录系统的关键 (非认知模式),生成内容加密密钥,进行内容的加密处理。 通过这种构成,可以清楚地识别出两个数据记录系统,防止了作为复制控制信息和掩埋CCI(嵌入式CCI)的EMI不匹配的发生。

    • A key providing apparatus capable of providing, to a predetermined terminal apparatus, a key for use in encrypting or decrypting data. The key providing apparatus comprises an acquiring part that acquires a directed graph formed such that at least one directed branch connects coordinate points in a coordinate system including a plurality of coordinate points with which subsets representative of combinations of terminal apparatuses are associated; an extracting part that extracts information of all of the directed branches included in a directed path connecting the starting point of the directed graph and a predetermined coordinate point; and a key generating part that generates, based on the directed graph, a key associated with a subset to which a predetermined terminal apparatus belongs. The key providing apparatus provides the information of the directed branches to the predetermined terminal apparatus.
    • 一种密钥提供装置,能够向预定的终端装置提供用于加密或解密数据的密钥。 钥匙提供装置包括:获取部件,其获取形成为使得至少一个有向分支连接坐标系中的坐标点的有向图,所述坐标系包括表示终端装置的组合的子集的多个坐标点; 提取部分,其提取包括在连接有向图的起始点和预定坐标点的有向路径中的所有有向分支的信息; 以及密钥生成部,其基于有向图生成与预定终端装置所属的子集相关联的密钥。 密钥提供装置将定向分支的信息提供给预定终端装置。
