ElGamal digital signature has numerous applications in real time situations. Due to its utility and popularity, security threats and challenges are increasing day by day for this signature scheme. This paper introduces a variant of ElGamal signature scheme, mainly after analyzing the existing weaknesses of the scheme where the security depends on one private key only. To overcome this, our scheme consists of a private key pair and an additional random number which makes the relation between the secret key and the randomly chosen number used more complicated. The cryptographic security of the proposed scheme is relatively much higher than the existing ElGamal signature scheme in literature.
