摘要： An information storing device includes a storage section configured to store revocation information that is a list of an identifier of an unauthorized device, and a data processor configured to execute determination processing of unauthorized equipment in accordance with the revocation information. The data processor extracts version information enabling identification of the issue order of the revocation information from the revocation information and transmits the extracted version information to a communication counterpart device. If the data processor receives the revocation information of a new version of the issue order held by the communication counterpart device from the communication counterpart device, the data processor executes revocation information synchronization processing of substituting the received revocation information of the new version for the revocation information of an old version stored in the storage section to store the revocation information of the new version.
摘要翻译：信息存储装置包括：存储部，其被配置为存储作为未授权装置的标识符的列表的撤销信息;以及数据处理器，被配置为根据撤销信息执行未授权设备的确定处理。数据处理器提取能够从撤销信息中识别撤销信息的发布顺序的版本信息，并将提取的版本信息发送到通信对方装置。如果数据处理器从通信对方装置接收到由通信对方装置保持的发布顺序的新版本的撤销信息，则数据处理器执行撤销信息同步处理，将接收到的新版本的吊销信息替换为撤销信息存储在存储部分中以存储新版本的撤销信息的旧版本。

摘要： An information processing apparatus includes a data processing section for reproducing contents stored in a medium having a general purpose area in which encrypted contents and corresponding utilization controlling information are stored and a protected area including a plurality of blocks having access limitation set thereto and including a block having an encryption key for decrypting the encrypted contents stored therein. The data processing section acquires utilization controlling information corresponding to a content from the general purpose area, decides, based on the utilization controlling information, whether validity period information indicative of a content utilization permission period is to be acquired from the utilization controlling information or the encryption key storage block, acquires the validity period information based on a result of the decision and then compares the acquired validity period information and current date information to decide permission or inhibition of content reproduction.
摘要翻译：信息处理装置包括：数据处理部分，用于再现存储在其中存储加密内容和对应的利用控制信息的通用区域的介质中的内容，以及包括具有设置到其中的访问限制的多个块的保护区域，具有用于解密存储在其中的加密内容的加密密钥。数据处理部从通用区域获取与内容对应的利用控制信息，根据利用控制信息，从利用控制信息或加密中取得表示内容使用许可期间的有效期信息密钥存储块，基于决定结果获取有效期信息，然后比较获取的有效期信息和当前日期信息，以决定内容再现的允许或禁止。

摘要： An information processing system includes a medium storing contents for reproduction, and a reproducing device to reproduce the contents. The reproducing device obtains a device certificate and transmits the device certificate to the medium. The device certificate includes the reproducing device's type information, and the medium encodes a media ID for identifying the medium according to an encoding algorithm selected according to the reproducing device's type information. The encoded media ID is transmitted to the reproducing device, which decodes the encoded media ID according to a decoding algorithm corresponding to the device type of the reproducing device, and decrypts and reproduces data to which the obtained media ID is applied.
