An Efficient Identity Based Strong Designated Verifier Signature Scheme
Peng Yan · Journal of Sichuan University · 2009
Some identity based strong designated verifier signature schemes proposed in the past years have some flaws in the security analysis.In order to solve these problems the security properties of the identity based strong designated verifier signature scheme was illustrated.Then a novel identity based strong designated verifier signature scheme was presented from bilinear map.Finally,the security of the presented scheme was strictly proven 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 present scheme has lower computational cost and shorter size of signature.
