摘要:
The present invention provides a method of validating a certificate by a certificate validation server using certificate policy and certificate policy mapping in a public key infrastructure (PKI). If the certificate validation server receives, from a client, an object certificate to be validated, a certificate of a certification authority which the client trusts, and a certificate policy which will be applied to validation of the object certificate, and receives a request for validation of the object certificate, the certificate validation server creates a certification path for the object certificate in response to the request. The certificate validation server validates the created certification path using a certificate policy mapping table if the validation of the object certificate is allowed, and then transmits a result message to the client according to the result of the validation of the certification path.

摘要:
The present invention provides a method for modifying validity of a certificate in a public key infrastructure (PKI)-based authentication system, which is capable of performing online suspension, recovery and revocation of a certificate between a user system and a certificate authority by executing user authentication with guaranteed reliability using user biometric information. Accordingly, there is no need for the user to personally visit a registration authority or certificate authority to modify the certificate validity. The user can easily modify the certificate validity using his/her user system connected online to the certificate authority.
