Validation Method of Certificate Validation Server using Certificate Policy Table and Certificate Policy Mapping Table in PKI

PURPOSE: A method for verifying the certificate in a certification verification server by using a public-key infrastructure certificate policy and a certificate policy is provided to concentrically manage the certification policy in the domain by processing the verification of the certificate in the certificate verification server. CONSTITUTION: A method for verifying the certificate in a certification verification server by using a public-key infrastructure certificate policy and a certificate policy includes a first step of: receiving the verification request of the verification target by receiving the certification policy to be applied to the verification target certificate from the clients(100,200), the certificate of authenticate agency and the verification target certificate; a second step of generating the certificate path of the verification target certificate corresponding to the request by the certificate verification server(300); a third step of determining the verification status of the verification target certificate by using the certificate policy table; a fourth step of performing the certificate path verification created by using the certificate policy table in the certificate verification server(300); and a fifth step of transmitting the success message when the result of the certificate path verification is successful and transmitting the failure message when the result of the certificate path verification is fail.
