In the traditional signature techniques, anyone can verify the signed message. It may cause a problem since a receiver of the signature can transfer the conviction of signature to a third party. In 1996, Jakobsson introduced a designate verifier signature(DVS) which is allowed to verify only specific verifier. DVS is the solution of conflict between authenticity and privacy because it provides message authentication without non-repudiation property. In this paper based on the notion of certificateless, we suggest a certificateless strong designated verifier signature scheme including the notion of strong which provides privacy of the signer. We suggest a scheme which is first trial to propose a certificateless strong designated verifier signature scheme including the notion of strong and non-delegatability, although it is not more efficient than previous one.
