Abstract :
In this study, a convertible undeniable signature scheme based on the El-Gamal signature scheme is proposed. The proposed scheme satisfies the undeniable property and can convert the undeniable signature to the ordinary one. The number of public keys and signatures are less than those of Boyar´s scheme (1991). It also reduces the number of communication steps of the signature confirmation protocol
