摘要
针对传统无证书签名方案中公钥和公钥持有者之间缺乏认证的问题,提出了一种基于密钥捆绑的无证书签名方案。在随机预言机模型和Inv-CDH困难问题假设下证明了方案的安全性。同时与其他无证书签名方案进行了效率比较,结果表明所提方案在计算效率上有一定优势,适用计算能力受限的物联网应用场合。
Aiming at the problem of lack of authentication between the public key and public key holder in the traditional certificateless signature scheme,a certificateless signature scheme based on key binding is proposed.And the security of the scheme is ensured by the random oracle model and the assumption of Inv-CDH difficulty.At the same time,efficiency comparison with other certificateless signature schemes is carried out.The results show that the scheme has certain advantages in computational efficiency which is suitable for applications of Internet of Things with limited computational power.
