摘要： The invention provides an enciphering apparatus and method, a deciphering apparatus and method and an information processing apparatus and method by which illegal copying can be prevented with certainty. Data enciphered by a 1394 interface of a DVD player is transmitted to a personal computer and a magneto-optical disk apparatus through a 1394 bus. In the magneto-optical disk apparatus with which a change to a function is not open to a user, the received data is deciphered by a 1394 interface. In contrast, in the personal computer with which a change to a function is open to a user, the enciphered data is deciphered using a time variable key by a 1394 interface, and a result of the decipherment is further deciphered using a session key by an application section.

摘要： An information processing system and method using an encryption key block sets sub-trees classified based on data processing ability of the devices (capability) in a key tree in which respective keys are corresponded to a root, nodes and leaves of a tree in which a plurality of devices are constituted as the leaves, generates a sub-enabling key block which is effective for an entity in a managing subject of each sub-tree (entity), and generates an enabling key block decodable only by the entities having common capability. Also, an information processing system and method using an encryption key block manages a partial tree of a key tree (sub-tree), generates a sub-enabling key block based only on a key set corresponding to nodes or leaves included in the sub-tree, and generates an enabling key block decodable only by selected entities by using the sub-enabling key block. Thus, it is possible to generate and distribute an enabling key block corresponding to data processing ability of a device and to manage devices by dividing a hierarchical key tree structure.

摘要： A data processing system, recording device, data processing method and program providing medium are provided to execute authentication processing and content storing processing between apparatuses. Program localization is employed to restrict access to program content. A plurality of key blocks store key data for authentication processing. Key block designation information is set in a recorder/reproducer, which is configured for executing authentication processing with the recording device by designating a key block. The recorder/reproducer can set a key block for each product, model or the like. In addition, data stored according to a selected key block cannot be utilized in a recorder/reproducer in which a different key block is set. Furthermore, an encryption processing controlling section of a recording device executes control in accordance with a pre-defined setting sequence. Furthermore, an illegal instrument that has not completed the authentication processing can be prevented from utilizing program content.

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： The present invention provides a configuration for preventing each entity code stored in information recording media from being leaked. Authoring studio code (ASC) and disc manufacturer code (DMC) are encrypted without failure and the encrypted codes are stored in information recording media. The data setting location in program map table (PMT) is controlled such that these entity codes will not overlap the seed area that provides key generating information, so that, if the packet storing the program map table storing authoring studio code (ASC) and disc manufacturer code (DMC) is set to an arbitrary position in a content packet sequence, these entity codes will not overlap the seed area that is non-encrypted data, thereby preventing these entity codes from being leaked outside.

摘要： The present invention provides a configuration capable of effectively preventing an encrypted content stored on an information-recording medium from being misused. In this configuration, a seed (seed 2) required for generating a block key to be applied to a process to decode an encrypted content is stored as information encrypted by using another block key Kb1. In addition, in a configuration where the seed (seed 2) needs to be transferred from a device to another, both the seed (seed 2) and a recording key K2 are transferred from the device to the other as information encrypted by using a session key. In such configurations, it is difficult to analyze the seed (seed 2) by acquisition of data from the information-recording medium or a data transmission line. Thus, difficulties to analyze a key generated by using the seed and analyze an encryption algorithm are increased. As a result, protection of contents at a high level of security can be implemented.

摘要： A disk drive (10) includes a plurality of thin-film members (36) for respectively covering the desired contour portions in a plurality of suspension arms (26) of an actuator (20). Each thin-film member (36) is fixedly attached to the surface of the suspension arm to cover the contour portion around a through hole (34) formed in the corresponding suspension arm (26) for reducing the moment of inertia, so as to cover the through hole. The thin-film member (36) substantially makes the contour portion around the through hole of the suspension arm (26) flush, and the air flow caused around the storage disks (16) rotating at high speed is guided smoothly along this contour portion. As a result, the air flow is stabilized, and the influences such as vibration on the actuator (20) are suppressed.
