Chang et al proposed a robust fail-stop blind signature scheme based on bilinear pairings. However, in this paper, it will be found that there are several mistakes in Chang et al＇s fail-stop blind signature scheme. Moreover, it will be pointed out that this scheme doesn＇t meet the property of a fail-stop signature： unconditionally secure for a signer. In Chang et al＇s scheme, a forger can forge a valid signature that can＇t be proved by a signer using the ＂proof of forgery＂. The scheme also doesn＇t possess the unlinkability property of a blind signature.展开更多
