A SECURE ID-BASED STRONG DESIGNATED VERIFIER SIGNATURE SCHEME

摘要：

Identity-based designated verifier signatures allow a signer to designate a specific verifier by using a simplified public identity such as name or IP address. In such a way, only the designated verifier can check the validity of signatures. In this paper, we present an ID-based strong designated verifier signature (IBSDVS) scheme from bilinear pairings, and provide the security proofs and efficiency analysis for the proposed scheme. Our IBSDVS scheme not only satisfies all the security requirements of the designated verifier signatures in identity-based cryptography, but also needs lower communication and computational cost.
