Partially blind signature is an extension of blind signature that allows a signer to sign a partially blinded message that include preagreed information such as expiry date or collateral conditions in the resulting signatures. It is more useful than blind signature in many applications, such as electronic cash (e-cash) system. Recently, Huang and Chang proposed a new design of efficient partially blind signature scheme. However, in this paper, we show that Huang–Chang partially blind signature… CONTINUE READING
