摘要： A configuration for achieving efficient content verification processing based on hash values is provided. Hash values of hash units set as segmented data of a content stored on an information storage medium are recorded in a content hash table and are stored on the information storage medium together with the content. An information processing apparatus for executing content playback executes hash-value comparison processing based on one or more randomly selected hash values. Regardless of the data amount of content, the configuration can perform hash-value determination and comparison processing based on hash units having a small amount of data, so that user equipment for executing content playback can perform efficient content verification.

摘要： A virtual machine can be implemented by anyone because the interface and other information necessary for implementation are publicly available. Therefore, it is possible that by implementing the virtual machine illegitimately, programs run thereon on will be made to operate illegitimately instead of legitimately. A program compares secret information held by the virtual machine with verification information held by the program itself. The program thereby verifies whether the virtual machine that runs the program is implemented legitimately, and is able to reject an illegitimate virtual machine.
摘要翻译：虚拟机可以由任何人实现，因为实现所需的接口和其他信息是公开的。因此，有可能通过非法实施虚拟机，在其上执行的程序将被非法地而非合法地运行。程序将由虚拟机保存的秘密信息与由程序本身保存的验证信息进行比较。该程序从而验证运行程序的虚拟机是否合法实现，并且能够拒绝非法虚拟机。

摘要： In a process for manufacturing an information recording medium, a configuration is provided in which strict information management and an information recording medium manufacturing process are realized. In a configuration in which master data as original data of recording data for an information recording medium is generated and recording data for the information recording medium is generated on the basis of the master data, master data containing a dummy data area in a partial area of the master data is generated, and the dummy data area is identified and a process for setting significant information is performed on the basis of the stored information of an auxiliary file. Therefore, it is not necessary to obtain data of significant information when the master data is to be generated, and it becomes possible to generate the master data without obtaining specific information, such as an encrypted key block.

摘要： A virtual machine can be implemented by anyone because the interface and other information necessary for implementation are publicly available. Hence, if virtual machine is implemented maliciously, a program operating thereon can be made to operate maliciously instead of operating legitimately. By comparing secret information held in memory and specific to the virtual machine with verification information which a program holds itself, the program verifies that the virtual machine on which it is running has been legitimately implemented and excludes illegitimate virtual machines.

摘要： An information processing system and method are disclosed in which information processing is performed using an enabling key block (EKB) in association with a tree structure including category subtrees. A key tree is produced, which include subtrees that are grouped in accordance with categories and are managed by category entities. The EKB includes data produced by selecting a path in the key tree and encrypting a higher-level key in the selected path using a lower-level key in the selected path. The EKB is then provided to a device. A requester, which requests production of the EKB, may produce a root key or may request a key distribution center (KDC) to produce a root key. If the (KDC) produces the EKB, it may also request a category entity to produce a sub-EKB.

摘要： An information processing device, information processing method and a recording medium are provided. Storage included in the information processing device is operable to store a node key and a leaf key, the leaf key being unique to the information processing device and the node key being unique to each node of a hierarchical network of nodes having a hierarchical tree structure. A decryption processor performs decryption processing to detect whether an encrypted decryption key for decrypting encrypted data is stored in at least one of on the information processing device or on a recording medium. When the encrypted decryption key is detected, the decryption processor is operable to calculate the decryption key by decrypting the encrypted decryption key. However, when the encrypted decryption key is not detected, the decryption processor is operable to calculate the decryption key by decrypting a key block using one of the one or more node keys stored in the storage and the leaf key stored in the storage. The calculated decryption key may then be encrypted and stored by the decryption processor on at least one of the recording medium or the memory.
