Abstract(in English) | Our research group has proposed the anonymous authentication scheme using user's attributes. In this scheme, the user can anonymously convince a verifier of the possession of attributes specified by the service provider with the complexity independent of the number of attributes. Previously, we have implemented Web system where the user proves the AND relations to a verifier. However, we cannot prove CNF fomulas that is the conbination of AND and OR relations at our Web system. In this study, we implemented the anonymous attributes authentication system for CNF fomulas using proxies and a questionnaire service as a Web service. We measured the communication times including the authentication times. The results show that our system is sufficiently practical. |
