METHOD FOR GENERATING CERTIFICATION PATH USING VERIFICATION SERVER ON PKI

摘要

PURPOSE: A method for generating a certification path using a verification server on the PKI(Public Key Infrastructure) is provided to reduce client's load by making the verification server process a certification path generating work instead of the client, and effectively perform the certification path generation by previously generating/storing the certification path and reusing the certification path. CONSTITUTION: The verification server connecting to the client collects a certificate from a linkable certification organization, and generates/stores the certification path realized by the certificate. When the client requests certification by providing the certificate to the verification server(321), the verification server checks that the certification path for the certificate is stored(322). In case that the certification path is existed(323), the verification server verifies the certificate by using the existed certification path, and transmits a verification result to the client.
