Abstract :
In current ring signature schemes, there is no distinguishing about the ranks of members of the ring. This paper proposes a ring signature scheme which considers the members´ rank values. We show our scheme is anonymous against full key exposure attack and unforgeable with respect to insider corruption in the standard model with the computational Diffie Hellman (CDH) and Subgroup Hiding (SGH) assumptions in bilinear groups.
