Abstract: In a strong designated verifier signature scheme, no third party can verify the validity of a signature. On the other hand, non-delegatability, proposed by Lipmaa, Wang and Bao, is another stronger notion for designated verifier signature schemes. In this paper, we formalize a security model for non-delegatable identity based strong designated verifier signature (IDSDVS) schemes. Then a novel non-delegatable IDSDVS scheme based on pairing is presented. The presented scheme is proved to be non-delegatable, non-transferable and unforgeable under the Gap Bilinear Diffie-Hellman assumption.
