New Short Group Signature Scheme without Random Oracles

Yuan Yan

Abstract

On the basis of BBS short group signature scheme,this paper construct a new short group signature scheme based on the SDH assumptions and the Decision Linear assumption.The scheme is proved to satisfy the security of thfull anonymity and full traceability.Compared with the latest schemes secure in the standard model,this scheme has a shorter length of group signature and higher operating efficiency,and allows new members to join in the group.
