Open full text 3 citations

Abstract

A new variant of the ElGamal signature scheme called "a Generalized ElGamal signature scheme" is proposed in 2011. The Generalized ElGamal signature scheme is a modified ElGamal signature scheme. In this paper, we propose the security proof of the Generalized ElGamal signature scheme in the random oracle model. First, we recall some security notions of signature schemes and show the security of the modified ElGamal Signature scheme.
