A new undeniable signature scheme on general linear group over group ring

Abstract

The concept of undeniable signature scheme was put forward by D. Chaum and H. van Antwerpen in 1989. Such signature scheme requires the signer’s co-operation at the verification step which defends the signer against the verification of his/her signature by an unwanted entity. In this paper, we propose a new undeniable signature scheme in a non-abelian group over group ring whose security relies on the difficulty of solving Factorization with Discrete Logarithm Problem (FDLP).
