There are a variety of certificates to prove the identity and the attribute on network. The public key certificate is used to prove the identity of the user. And the attribute certificate is used to prove the attributes of the user. It is necessary to bind the attribute certificate to the public key certificate to prove the owner of the attributes because the attribute certificate doesn't contain the public key information. Some attributes have derivation attributes. Some derivation attributes are associated with the original attributes. Therefore, the derived attributes should be revoked when the original attributes are revoked. It is necessary to do it at once. The naive methods for processing the attribute certificate does not have the direct relationship with the derivation attributes. But the naive methods have the problems. First, the relationship among attributes are not written into the attribute certificate. The other, the attribute certificate cannot be revoked at once. In this paper, we propose the attribute authentication method with relationship among attributes. So our method makes it possible that verifier verifies the attribute certificate with complex relationship and make void by revocation.
