摘要
针对目前基于身份的强指定验证者签名方案可授权及效率不高的问题,提出一种基于身份的强指定验证者签名方案。对基于双线性对的签名方案进行安全性证明以及效率分析。性能分析结果证明,与已有方案相比,该方案满足不可传递性、不可伪造性及不可授权性,双线性对运算和模乘运算相应减少,签名效率更高。
Aiming at the delegatability and inefficiency problems of current identity-based strong designated verifier signature schemes, a new efficient identity-based strong designated verifier signature scheme is proposed, which includes signature scheme based on bilinear pairings, security proof and efficiency analysis, performance analysis results show that the new scheme can satisfy the security requirements of non-transferability, unforgetability, non-delegatability. Compared with other existing schemes, the new scheme which reduces the computational cost ofbilinear pairings and modular multiplication is more efficient.
