摘要： A configuration is provided which improves scrambling processing of content and eliminates unauthorized use of content. Scramble rules which differ for each content are used for content scrambling processing. For example, in the event of using shuffling processing, various shuffle states are specified as scramble rules. In the event of using Exclusive-OR processing, a value applicable to EXOR is specified as the scramble rule. Also, in the event of using rotation processing, a shift amount is specified as the scramble rule. In the event of using 32 shuffle elements in shuffling processing, 32! different shuffle states, that is to say, 32! different scramble rules can be specified. Also, the values for EXOR or the rotation shift amount can be set as various values, and many scramble rules can be set.

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： 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： 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： An information reproducing method and an information reproducing device in which the key renewal block (KRB) of the latest version is selectively used to encrypt the content to store the encrypted contents in a recording medium. A plural number of KRBs of different generations and versions are stored in a recording medium. If the latest KRB is detected, it is stored in a memory unit within the recording and/or reproducing device. A plural number of KRBs having plural different generations or versions are stored on the recording medium. With the present method and device, in storing the content in the recording medium, the latest usable one of the KRB in the memory unit of the reproducing device and plural KRBs on the recording medium is detected to acquire an encrypting key, such as a media key, to execute the content encryption. In this manner, the encrypted content based on a KRB of a newer version can at all times be stored on the recording medium.

摘要： An information processing system and method are disclosed in which information processing is performed in a highly efficient manner using an enabling key block (EKB) on the basis of a tree structure including category subtrees. A key tree is produced so as to include a plurality of subtrees that are grouped in accordance with categories and managed by category entities. An EKB is produced so as to include data produced by selecting a path in the key tree and encrypting an upper-level key in the selected path using a lower-level key in the selected path. The resultant EKB is provided to a device. If a change occurs in state of a category tree capable of processing an EKB identified in the EKB type definition list, a notification of the change in state is sent to an entity that uses the EKB thereby making it possible for an EKB requester to perform processing in accordance with a newest EKB.

摘要： A configuration is provided wherein usage restrictions of an application are determined in accordance with timestamps. A certificate revocation list (CRL) in which the revocation information of a content owner who is a providing entity of an application program recorded in a disc is recorded is referred to verify whether or not a content owner identifier recorded in an application certificate is included in the CRL, and in the case that the content owner identifier is included in the CRL, comparison between a timestamp stored in a content certificate and a CRL timestamp is executed, and in the case that the content certificate timestamp has date data equal to or later than the CRL timestamp, utilization processing of the application program is prohibited or restricted. According to the present configuration, a configuration is realized wherein an unrevoked application is not subjected to utilization restriction, and only a revoked application is subjected to utilization restriction.
