摘要： A history file that an IC card received from a receiver is confirmed to be a proper history file, so that a repeat input of a license can be prevented. A server (100) which transmits a license that has a usage condition of content includes: a classification key generating unit (101) which generates a classification key that has a history file ID for uniquely identifying each of a plurality of history files on which license-input history on the receiver side is recorded, the license-input history being distributed among the history files; a license issuing unit (103) which issues a license that has the usage condition of content in association with the classification key generated by the classification key generating unit (101); and a server communicating unit (104) which transmits the classification key and the license associated with the classification key.

摘要： An IC card (processing terminal) divides a process into process blocks, and holds a time period required for processing each process block. A receiver (receiving terminal) notifies the IC card of a time period which can be spent for processing non-real-time process data when causing the IC card to perform the processing. The IC card processes the process blocks which can be processed within the notified time period. After the processing, the IC card once sends a response back to the receiver, and then transitions into a state in which it can receive a new request. Accordingly, it becomes possible for the IC card to process real-time process data such as an ECM. In the case where the receiver continues the suspended processing, it notifies the IC card of the continuation of the processing so that it causes the IC card to continue the processing of non-real-time process data.
摘要翻译： IC卡（处理终端）将处理划分为处理块，并保持处理每个处理块所需的时间段。接收机（接收终端）在IC卡执行处理时向IC卡通知可用于处理非实时处理数据的时间段。 IC卡处理可以在通知的时间段内处理的处理块。在处理之后，IC卡一次将响应发送回接收器，然后转换到可以接收到新请求的状态。因此，IC卡可以处理ECM等实时处理数据。在接收器继续暂停处理的情况下，它向IC卡通知继续处理，使得IC卡继续处理非实时处理数据。

摘要： Security is secured according to the type of a license so that unnecessary processing load is reduced. A license accumulation control unit (102) and a license transfer control unit (103) identifies a usage-rule type (204) which indicates whether or not a license (200) includes a usage rule (205) which requires updating each time a content is used, and encrypts the license (200) by using different encrypting methods depending on whether or not the usage rule (205) is included in the license (200). The license accumulation control unit (102) encrypts a content key: with a domain key when the license 200 does not include the usage rule (205); and with a license management device unique key, when the usage rule (205) is included, and accumulates the encrypted key in a license accumulation unit (110). The license transfer control unit (103), when the license (200) does not include the usage rule (205), reads the license (200) from the license accumulation unit (110) and transfers the license (200) with encryption maintained by using a license transfer unit (transfer method B) (105).
