Abstract

The invention provides a digital blind signature technique for forgery to stop instantly. It enables the signer to proof forgery signature. It also provides the protection for anonymous user. This technique is mainly based on the RSA public key secret code system. It is suitable for the application of electronic payment or electronic voting system with higher security requirement having many users. It can also transform to discrete logarithm (such as DSA) and elliptic curve (such as ECDSA) public key secret code system. It can satisfy different secret code requirements for different users.
