| Outline of Final Research Achievements |
By anonymous authentications, a user can be anonymously authenticated, and thus the privacy of users is protected. In conventional anonymous authentication schemes, large data size and large processing time are required for user revocation and excluding anonymous dishonest users. In this study, to realize practical anonymous authentications in mobile environment, we have constructed efficient schemes for the user revocation and excluding anonymous dishonest users.
