Strong Designated Verifier ID-Based Ring Signature Scheme

In this paper, we propose a new strong designated verifier ID-based ring signature scheme. The proposed scheme provides a way to generate a signature to only a designated verifier anonymously by one of the ring members. Except for the verifier, no one knows that the signature is generated by a ring member or the designated verifier. We show that our scheme can satisfy all the strong designated verifier security properties and has a better computational efficiency.
