Abstract
This paper proposes a new attack method on digital signature scheme. Some signature schemes which have design defect can been broken through this method. In this method, some signature datum will be constructed into identical base datum, anyone could employ this way to attack and forge a valid signature. At the same time, some examples are given to illustrate the status of design defect in these signature schemes.
