An efficient non-delegatable identity based strong designated verifier signature scheme

Designated verifier signatures are intended to a specific and unique designated verifier, who is the only one person to check their validity. This paper proposes a new efficient non-delegatable strong designated verifier signature scheme based on identity based cryptography. We analyze the security of the scheme and compare its computational aspects with the other ID-SDVS schemes existing in literature and the result shows that our scheme is more efficient as compared to others.
