摘要：

At Crypto'99 Dr Coron, Naccache, and Stern presented a signature forgery strategy of the RSA digital signature scheme. The attack is valid on Chaum's blind signature scheme, which has been applied to many practical applications such as electronic cash and voting. In this paper we propose a method to inject a randomizing factor into a message when it is signed by the signer in Chaum's blind signature scheme such that attackers cannot obtain the signer's signatures of the: special form for the attack.
