Deng Cong-zheng · Journal of Chengdu University · 2006
The digital signature is an important technique that guarantees the security of information in the realm of cryptography,The security of ElGamal digital signature is based on the difficulty in solving the discrete logarithm.This paper introduces an arithmetic method on counterfeiting signature and analyzes aod evaluates the security of the whole signature system.
