摘要： A content key, an authentication key, and a program data etc. are transmitted with an enabling key block (EKB) in an encrypted key constitution of a tree structure. The EKB has a constitution in which a device as a leaf of the tree holds a leaf key and a limited node key, and a specific enabling key block (EKB) is generated and distributed to a group specified by a specific node to limit devices that can be renewed. As the devices that do not belong to the group cannot perform decryption, the security for distributing keys etc. can be secured. Thus, distribution of various kinds of keys or data is executed in an encryption key constitution of a tree structure to realize an information processing system and method enabling to distribute data efficiently and safely.

摘要： When a player cannot play back data because a master key held by the player has a generation older than the generation of a master key having been used for recording the data, or when a recorder cannot record data because a master key held by the recorder has a generation older than the generation of a master key necessary for recording to a recording medium, the user is prompted to renew the master key for acquisition of the necessary master key, thereby enabling the data playback or data recording. The renewed master key is distributed in such a form that can be processed by a specific device via a transmission medium such as a recording medium, network, IC card, telephone line, for example, via a tree-structured distribution system.

摘要： An enabling key block (EKB) used in an encrypted key distributing tree structure is generated by forming a simplified 2-branch or multi-branch type tree with a terminal node or leaf which is capable of decrypting on the basis of a key corresponding to a node or a leaf of the simplified tree. Further, the EKB includes a tag for indicating a position of an encrypted key in the tree. The tag not only discriminates position but also stores data for judging the presence of encrypted key data within the EKB. As such, a considerable reduction in data quantity is realized, and the decrypting process in a device is also simplified.

摘要： Apparatus and method for processing information may determine whether a migration condition exists by a source information processing unit executing a program. When a migration condition is determined to exist by the source information processing unit, a destination information processing unit may determine whether an instruction to be executed of the program is a predetermined instruction. The instruction to be executed is converted by an instruction emulator, when a result of a determination by the destination information processing unit is the predetermined instruction.

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.
