Cryptanalysis of One Fair E-cash System

LiHua Liu and Zhengjun Cao

Abstract

One fair e-cash system was proposed in [1]. In this paper, we show that the system is insecure. Besides, we point out that there are two drawbacks. One is that those integer intervals for are unappropriate. The other is that the datum in signature data is redundant. Moreover, we give a minute description of the technique to shun the challenge in the scheme. We think the method is a little interesting.
