This paper describes a partial blind signature scheme based on the theory of bundling homomorphism. Analysis of the scheme shows by induction that an adversary with polynomial computing ability can neither forge a partial blind signature that can be verified nor sign a message but successfully deny signing it later.An adversary with infinite computing ability can forge a partial blind signature that can be verified,but it can be easily found.Therefore,this scheme can guarantee the benefits of both signer and nominee,and the privacy of the nominee.
