| Abstract(in English) | While various Web services have spread, a lot of private information leaks have been often caused by the service vendors. One method to solve this problems is the use of the anonymous authentication based on group signatures. Group signatures allow the service vendors to verify that a signature is signed by a valid user, but they cannot know who is the signer. Therefore, the anonymous authentication based on group signatures can protect user's privacy while preventing illigal access. In this paper, we implement a privacy enhancing SSL/TLS protocol based on group signatures with membership revocation that does not need the change of user's certificate, and evaluate the authentication time. In a group with 5000 members where 10% of its members are revoked, the authentication needs about 3 seconds. This result shows the practicality of this anonymous authentication protocol for a medium scale group. |
