摘要： A user can watch desired content among a plurality of encrypted contents recorded in a storage apparatus having a large capacity recording medium when the user wants to watch. Usage Pass (UP) necessary for watching content and encrypted content are recorded in a rental storage apparatus. The UP is in an invalid state when the storage apparatus is rented, and processing for validating the corresponding UP is executed between the storage apparatus and a host apparatus through which content is watched to thereby make content watchable. A history that processing for validating the UP is executed is recorded in the storage apparatus. A service provider bills a content use fee to the user based on the history of the storage apparatus.
摘要翻译：当用户想要观看时，用户可以在记录在具有大容量记录介质的存储装置中的多个加密内容中观看期望的内容。用于观看内容和加密内容所需的使用通行证（UP）被记录在租赁存储装置中。当存储装置被租用时，UP处于无效状态，并且在存储装置和通过其观看内容的主机装置之间执行用于验证相应的UP的处理，从而使内容可以观看。执行用于验证UP的处理的历史被记录在存储装置中。服务提供商根据存储装置的历史向用户提供内容使用费。

摘要： The original content and the converted content obtained by converting the original content are encrypted by the same content key. A license containing data of use conditions such as the content key and a use period is recorded in an area of a storage medium limited for access. When the converted content is used with an external storage medium, a copy of an original license is created, a use period of the copy is changed to a use period of the converted content designated by a user, and the license is output as a converted content license to the external storage device. The use period of the original content is rewritten to prevent its overlapping with a use period defined by the converted license.

摘要： Embodiments of the present invention provide a simplified authentication transaction for reconnecting a storage device to a host apparatus that has completed authentication in the past. According to one embodiment, an authentication log is recorded in the host. Plural units of this log information are recorded in the storage device. At the time of transferring a content decryption key and usage rules between the host and the storage device, the decryption key and usage rules are recorded into the host as a log for the transfer. The used authentication log is recorded into the storage device as RAPDI. If RAPDI indicates the authentication log in the simplified authentication transaction, recovery transaction is permitted. The host device deletes/invalidates or holds the log for the transfer in accordance with non-permission/permission. In the case of permission, the key and usage rules are recovered by using a log for the transfer prior to the simplified authentication transaction.

摘要： A routing apparatus includes a plurality of routing units and function units. The routing unit receives a packet from each port, and uses header information contained in the packet to judge whether the packet should be transmitted to the function unit. In the case where the packet should be transmitted to the function unit, the routing unit adds a first identifier to the packet and transmits it to a transmission unit. The function unit receives the packet containing the first identifier from the transmission unit, and executes a predetermined processing for the packet. The function unit adds a second identifier to the packet and transmits it to the transmission unit.

摘要： A labor of disconnecting many cables is omitted even when carrying a file basestation with an external storage loaded together with a main body. An information processing unit comprises: a main body having a CPU, a keyboard and a display unit; a file basestation with an external storage, such as an FD·D or a CD-ROM·D, loaded; and a portreplicator with many connectors loaded. Removal of the main body alone from the portreplicator or removal of the main body and the file basestation can omit the labor of disconnecting many cables connected to the portreplicator.

摘要： Embodiments of the invention prevent a storage from being continuously used in a state in which the time of a built-in clock is different from the actual time because of replacement of a battery or intentional tampering of time. In one embodiment, a storage having a recording medium for storing content data includes: a clock that can refer to present time and can set time to reliable standard time on the outside (time synchronization); a built-in power supply that supplies power to the clock; and a nonvolatile memory that records time when the time synchronization for the clock is performed. The storage compares, according to circumstances, the present time indicated by the built-in clock and the time when the time synchronization is performed last time and, when it is made clear that the time synchronization is not performed for time longer than a fixed time set in advance, prohibits an access to a limited access area of the recording medium.

摘要： Encrypted data and an encryption key used for the encrypted data are separately stored and managed. A first storage device stores an encrypted data block, predetermined information and first management information. The predetermined information includes key data for decrypting the encrypted data block and includes a requirement for using the encrypted data block. The first management information is used to manage the encrypted data block and includes a first storage address at which the predetermined information is stored. A host device transfers the predetermined information from the first storage device to a second storage device, causes second management information including a second storage address, at which the transferred predetermined information is stored and which is included in the second storage device to be stored in the second storage device.
