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.

摘要： To provide a configuration in which a unit classification number corresponding to a content playback path is set based on various units. A unit classification number defining a playback path of content including encrypted data having different variations generated by encrypting a segment portion which forms the content by using a plurality of segment keys and encrypted content generated by encrypting a non-segment portion by a unit key is set based on various units, such as a content management unit and an index. In a CPS unit key file storing key generating information concerning CPS units as content management units, settings of unit classification numbers are indicated. Based on the CPS unit key file, a unit classification number to which content to be played back belongs can be obtained.
