| Abstract(in English) | Group signature scheme is one of signature schemes which keep signer's identity information secret. A pairing-based group signature scheme which can make a signer sign without any revocation information and has the short length of the signature was proposed. However this scheme has a problem that the anonymity cannot be proved in case of using the twisted pairing which is known for an efficient implementation of pairing. Then, in this paper, we extend the previous scheme to have the provable anonymity in case of using twisted pairing. In addition, we efficiently implemented the extended scheme by transforming some equations and introducing parallel processing, and then we show that the extended scheme can be executed for a practical time on a server with multi-core CPU even if about 500 members are revoked. |
