摘要

Anonymous authentication schemes, mostly based on the notion of group signatures, allow a group member to obtain membership from a server and gain access rights if the member can prove their authenticity to the verifier. However, existing authentication schemes are impractical because they neglect to provide an exclusive verification of the blacklist. In addition, the schemes are unaware of malicious members who are involved in privilege transferring. In this paper, a novel membership authentication scheme providing detection of membership transfer and proof of membership exclusiveness to the blacklist is proposed.
