Abstract (in Japanese) (See Japanese page) 
(in English) Group signature schemes with membership revocation have been intensively researched. In this paper, we propose a new group signature scheme where the computational cost for signing/verification is lower than an existing scheme without the update of signers' private keys. In the proposed scheme, a group manager issues the membership certificate with a unique prime number to every member of the group. A revocation of a membership certificate is performed by using this prime number. To show the practicality of the proposed scheme, we implemented the scheme on a PC, and measured the execution time. In a group with 1000 members, the signature
signing/verification needs about 1.3 seconds. Since this time is less than half of the time that needed in the existing scheme, the practicality of the proposed scheme is sufficiently shown.
