| Abstract(in English) | A certificate-based authentication system with a blind signature scheme (the anonymous authentication system) is a practical solution in order to protect a user's anonymity while verifying the user's rights. However, under some time sequences of obtaining/showing the certificate, the holder of the certificate can easily be inferred by the certificate-receiver. In this paper, we propose a novel authentication method using several certificates from the anonymous authentication system and a novel certificate with a ring signature at one time. Our method can verify a user's right without impairing the user's anonymity under any time sequences of obtaining/showing the certificate. |
