%X In a designated verifier proxy signature scheme, the original signer delegates his signing capability to the proxy signer in such a way that the latter can sign messages on behalf of the former, but only designated verifier can believe the validity of the signatures. The security of the known designated verifier proxy signature schemes is proven in the random oracle model. In this paper, based on Waters signature scheme, the first designated verifier proxy signature scheme is presented and is provably secure without random oracles. The proposed scheme is proven secure against existential forgery in adaptively chosen message attack under the weak Gap Bilinear Diffie-Hellman assumption.
