ElGamal Digital Signature Algorithm of Adding a Random Number

As for the problem that ElGamal digital signature scheme's security is constantly being challenged and increasingly becomes increasingly serious, an improved ElGamal digital signature algorithm is proposed. As the original ElGamal algorithm has its own security disadvantages that only one random number is used, in order to improve its security, the scheme presented in this paper improved this demerit by adding a random number to the original one and increasing difficulty of deciphering key. The security of the improved signature scheme is the same with the ElGamal signature scheme which is based on the difficult computable nature of discrete logarithm over finite fields.
