A New Efficient ID-Based Strong Designated Verifier Signature Scheme
Shi-Feng Sun, Qiaoyan Wen, Zhengping Jin, Hua Zhang · 2010
Recently, several ID-based strong designated verifier signature schemes have been proposed in the literature. However, most of them can not satisfy the strong ness property that any third party without the designated verifier's private key is unable to check the validity of a designated verifier signature, and they are not given the rigorous security proofs. To solve those problems above, we put forward a new efficient ID-based strong designated verifier signature scheme in this paper which is strong, and rigorously proved secure in the random oracle model based on the Bilinear Diffie-Hellmanassumptions.
