A New Type of Group Signature Scheme

Jun Zhong Dake He

Abstract

On the basis of BB short signature scheme, this paper derives a new signature scheme, from which we construct a new kind of group signature scheme. The security of the new group signature scheme is based on the q-Strong Diffie-Hellman assumption and the Decisional Diffie-Hellman assumption in the random oracle model. The length of the new group signature is a little longer than that of BBS short group signature. However, in the new group signature scheme, giving certificates and private keys to group members do not need any third trusted party, while in BBS short group signature scheme it does need.
