Comment on an Enhanced RSA-Based Partially Blind Signature

Abstract:

Hwang et al. showed that the Chien et al.'s partially blind signature scheme based on RSA public cryptosystem could not meet the untraceability property of a blind signature. Wen et al. and Wu et al. claimed that Hwang et al.'s attack is incorrect. Later, Fang et al. gave an improvement to against Hwang et al.'s method. In this paper, we pointed out some typographical errors in Wen et al. and Wu et al.'s article; and certained their claims are correction. Thus, the Fang et al. improved scheme may not becomes to be necessary. Chien et al.'s partially blind signature scheme is still satisfy the untraceability property.
