| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Conventional anonymous authentication such as group signature has a problem that the ID administrator can specify the authorized user. As a solution to this problem, anonymous authentication using a blacklist has been proposed. In this method, the user is authenticated without the ID administrator by proving that the past own session IDs are not included in the blacklist. However, since it can only perform a simple evaluation of whether he / she is an illegal or not. If a bad activity is performed, it becomes an illegal user at once. This evaluation does not depend on its degree. Thus, we propose a reputation-based blacklistable anonymous authentication in this research. The user receives a score from the service provider or other users after the session for his / her activity. When scores in sessions of all users and session IDs of the authenticated user are given, newly constructed accumulator can show "only" the sum of scores of the user. Since each information is compressed in the accumulator, it can be verified efficiently. By incorporating this into the previous scheme, we propose a reputation-based blacklistable anonymous authentication. Additionally, the processing time of authentication is measured by a PC to show the practicality. |
