%X Abstract:This paper presented a new zero-knowledge protocol for SDH, which was based on improved Cramer-Shoup encryption from DDH, TCRv, KEA3 assumption and SDH assumption. Using this protocol as a building block, constructed a new short group signature, which was provable secure in the BMW model, the scheme was of IND-CCA2-full-anonymity, and the signature was only 1 193 bit in size. Compared with other related works, this method was of higher efficiency and shorter size of group signature at the cost of strong assumptions.
