Identical base construction attack on digital signature scheme
Xiaoping Su · Journal of Computer Applications · 2010
This paper studied many digital signature schemes and had found them insecure because of the irrationality of these signature factors or the whole signature scheme,which made the attackers be able to transform the signature verification equation into a equation with the same base number and easily forge signature datum through the equation of the two exponents.The paper proposed a new concept:the attack based on identical base construction,and explicitly indicated that defects could be avoided in designing digital signature.Meanwhile,four examples were given to illustrate the insecurity in signature designing.Finally,some general ways to improve these signature schemes were provided
