Abstract :
In this paper, the authors first review Hwang el al´s a new multi-proxy multi-signature scheme and point out its disadvantages. To overcome the weakness, a nonrepudiable multi-proxy multi-signature scheme based on Hwang et al´s scheme, is proposed. The improved version can provide the fair protection for the original signer group and the proxy group. Moreover, it is secure against the forgery attack without the secure channel.
