Abstract: PROBLEM TO BE SOLVED: To reduce client's load in a certificate effectiveness verification system using a verification server in a public key infrastructure. SOLUTION: Whether a certificate is effective or not is processed by verification servers 1, 2 (28, 29) on the wired/wireless Internet having the public key infrastructure. An approval server list and a routing server list are set in the server 1 (28), and when these lists are included in a domain to be processed by the server 1, the server 1 directly processes both the lists. When those lists are included in an external domain, the server 1 transmits the lists to the verification server 2 (29) for verifying the effectiveness of the certificate of the approval domain by routing. Thus, mutual connection having approval relation can be attained when verifying the effectiveness of the certificate.
