摘要： A system including a secure LSI 1 establishes a communication path to/from a server 3 (UD1), and receives a common key-encrypted program generated by encryption with a common key and transmitted from the server 3 (UD6 and UD7). The received common key-encrypted program is decrypted to generate a raw program, and the raw program is re-encrypted with an inherent key to newly generate an inherent key-encrypted program, which is stored in an external memory.

摘要： A file-update apparatus, which can mount a removable information recording medium storing a FAT and a directory entry that show a storage location, on the medium, of data constituting a content of a file, and which executes a plurality of update procedures to update the file, records progress information showing which of the update procedures have been executed in updating the file into an internal memory having a continuous power supply. Even if an abnormal stoppage of the update procedures caused by a power-down or the like occurs during updating of the FAT, for example, the progress and update information remain in the memory. Thus, the FAT and the like can be re-updated and inconsistencies resolved using this information, after recovering from the abnormal stoppage.
摘要翻译：一种文件更新装置，其能够在介质上安装存储FAT和存储位置的目录条目的可移动信息记录介质，构成文件内容的数据，并且执行多个更新程序来更新该文件记录显示在将文件更新为具有连续电源的内部存储器中执行了更新程序的进度信息。即使在更新FAT期间发生由掉电等引起的更新过程的异常停止，例如，进度和更新信息保留在存储器中。因此，在从异常停止恢复之后，可以使用该信息来重新更新FAT等并且解决不一致。

摘要： A domain key is used to perform chaining decryption with respect to encrypted content key information (ST203-1), and first data is extracted (ST203-2). The extracted first data is compared with partial-check data (ST203-4). The first data as it is encrypted is extracted from the m pieces of encrypted content key information (ST203-6), and a predetermined operation is executed with respect to concatenated data including m extracted check values to generate second data (ST203-8). The second data is compared with whole-check data included in domain key information (ST203-11). If the first data matches the partial-check data (ST203-5) and the second data matches the whole-check data (ST203-12), it is determined that there is not tampering.
摘要翻译：域密钥用于对加密的内容密钥信息执行链接解密（ST203-1），并提取第一数据（ST203-2）。将提取的第一数据与部分检查数据进行比较（ST203-4）。从M个加密内容密钥信息（ST203-6）中提取加密的第一数据，对包含m个提取的检查值的级联数据执行预定的操作，生成第二数据（ST203-8 ）。将第二数据与包括在域密钥信息中的全检查数据进行比较（ST203-11）。如果第一数据与部分检查数据（ST203-5）匹配，并且第二数据与全检查数据（ST 203-12）相匹配，则确定没有篡改。

摘要： An information processing device that reads out and records data from and on an information recording medium includes a file system controller. File system control information is constructed in a system memory within the information processing device, and the file system controller unifies and controls a plurality of information recording media which are managed by individual file systems into a single virtual file system. In addition, the file system controller manages a priority order that indicates an information recording medium to be utilized with priority if files having the same name exist. This priority order can be changed in response to a request from an application program. Thus, the processor can unify and manage the plurality of information recording media and, also, enables the application to access all of the files having the same name.

摘要： A host device (1) adds host function information indicating a function of the host device (1) to a command and transmits it to a storage device (2). The storage device (2) receives the command transmitted from the host device (1) and determines whether the function indicated by the host function information can be processed. When the function can be processed, the function is processed based on the command. When the function cannot be processed, no response is returned or error information is returned. Thus, under simple control, it is possible to prevent data destruction by a host device of an old version.
摘要翻译：主机设备（1）将指示主机设备（1）的功能的主机功能信息添加到命令中，并将其发送到存储设备（2）。存储装置（2）接收从主机装置（1）发送的命令，并且确定是否可以处理由主机功能信息指示的功能。当功能可以处理时，该功能将根据该命令进行处理。当函数无法处理时，不返回任何响应或返回错误信息。因此，在简单的控制下，可以防止主机装置破坏老版本的数据。

摘要： A host device transmits a command from a command transmission unit (101a) along a predetermined command sequence. A storage device (2) receives the command in a command reception unit (202a). An access determination unit (202c) determines the sequence of the command transmitted from the host device (1) and determines that reception of the access to the host device (1) is enabled only when the sequence is identical with a predetermined sequence. Thus, with simple control, it is possible to prevent data destruction by a host device of an old version.

摘要： A card information-storing portion is provided in a semiconductor memory card, and information relating to access performance such as access condition and access rate is held in the storing portion. Further, an access device acquires the held information from the semiconductor memory card to make it possible that the information can be used for control of a file system. This optimizes processing of the access device and the semiconductor memory card independent of differences in characteristics of semiconductor memory cards and management methods used, realizing high-rate access from the access device to a semiconductor memory card.
