Analysis of ID-based restrictive partially blind signatures and applications
Partially blind signatures and restrictive blind signatures are two important techniques in electronic cash systems and voting systems. Restrictive partially blind signatures incorporate the advantages of these two blind signatures. Recently, ChenZhangLiu first proposed an ID-based restrictive partially blind signature from bilinear pairings (Chen, X.F., Zhang, F.G., Liu, S.L., 2007. ID-based restrictive partially blind signatures and applications. The Journal of Systems and Software 80 (2), 164171). However, in this paper, we show that ChenZhangLius scheme has a security weakness. Their scheme does not satisfy the property of restrictiveness as they claimed, and an account-holder cannot be revealed when double-spending happens.
