    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.
