PROBLEM TO BE SOLVED: To solve a problem that the accuracy of the certificate validation result of a certificate can not be secured because a cached CRL is not the latest one if the CRL is cached for an increased speed of a certificate validation process, when a certification authority issues the CRL in an urgent situation. SOLUTION: When the CRL is issued, the certification authority sends a CRL issuance notification to certificate validation servers. The certificate validation servers that receives the CRL issuance notification cache the latest CRL. Thus, the accuracy of the certificate validation result can be secured. COPYRIGHT: (C)2004,JPO
