Identity Based Undeniable Signatures
Abstract
In this paper, we give a first example of identity based undeniable signature using pairings over elliptic curves. We extend to the identity based setting the security model for the notions of invisibility and anonymity given by Galbraith and Mao in 2003 and we prove that our scheme is existentially unforgeable under the Bilinear Diffie-Hellman assumption in the random oracle model. We also prove that it has the invisibility property under the Decisional Bilinear Diffie-Hellman assumption and we discuss about the efficiency of the scheme.
