Partially Blind Signature

Partially blind signature is an important technique in secure electronic cash system. Recently, Zhang et al. presented the first certificateless partially blind signature scheme and constructed an electronic cash system based on this scheme. They claimed that their certificateless partially blind signature scheme is secure in the random oracle model. However, in this paper, we demonstrate the scheme is not secure. Our attack indicates that a malicious KGC in the electronic cash system based on Zhang et al.'s certificateless partially blind signature can forge valid electronic coins without being detected by the bank. It will result in loss of the bank.

Partially Blind Signature

A new partially blind signature scheme is proposed based on Schnorr blind signature scheme. Compared with the previous schemes, the proposed scheme has lower computations and shorter signature size. By conversely using the proposed partially blind signature, a fair e-payment protocol is given. An advantage of this protocol is that two participants achieve the goals of exchanging their items without intervention of a third party. The low computations and good properties of the underlying partially blind signature guarantee that the proposed protocol has needed efficiency and security.

Partially Blind Signature

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.
