Title:
A New Type of Group Blind Signature Scheme Based on Bilinear Pairings
Authors: Jun Zhong Dake He
Abstract:This paper constructs a new group blind signature scheme on the basis of CZK group signature scheme. The security of the new scheme is under the computational Diffie-Hellman problem in the random oracle model. In our scheme, to blind the group signature of CZK only adds the computation of modular addition; while the scheme in LR98 adds the computation of double discreet logarithm, root of the discreet logarithm and random permutation in order to blind the group signature of CS97. As far as the computation complexity is concerned, our scheme is more efficient than LR98.
