METHOD FOR PROVIDING ANONYMOUS PUBLIC KEY INFRASTRUCTURE AND METHOD FOR PROVIDING SERVICE USING THE SAME

摘要

A method for providing anonymous public key infrastructure and a method for providing service using the same are provided to guarantee anonymity to the user by providing the anonymous certificate connected with the real name certificate of the public key infrastructure. A method for providing anonymous public key infrastructure is applied to the system which includes a real name PKI service domain(100), a user terminal(200), and anonymous PKI service domain(300). The real name PKI service domain is the server including the certificate authority and certificate authority repository. The real name PKI service domain performs the issuance and storage of the real name certificate. The user terminal stores the real name certificate and the anonymous certificate. The user terminal receives the real name certificate. The user terminal requests the issuance of the anonymous certificate to the anonymous PKI service domain.
