some identity based strong designated verifier signature schemes have been proposed
but there are some drawbacks on these schemes. To overcome the problem above
in this paper
a novel identity based strong designated verifier signature scheme is proposed from bilinear map. The proposed scheme is secure in the random oracle model under the bilinear Diffie-Hellman assumption. From the performance comparison with the existing schemes
it can be concluded that the proposed scheme has lower computational cost and shorter size of signature.
