摘要
利用Chik How Tan加密方案对SDH对(A,a)进行加密,生成(A,a)的零知识证明协议,然后证明了该协议为诚实验证者在DBDH假设下对SDH对(A,a)的零知识证明.该协议适用于对数据的安全性要求较高的用户.与类似文献相比,该协议效率更高.
This paper presents a new zero-knowledge protocol for SDH pair(A,a),which is based on Chik How Tan encryption,then we prove that the protocol is an honest verifier zero knowledge proof of knowledge under DBDH assumption.The protocol is suitable for users with higher requirements for data security.Compared with[6],the protocol is of higher efficiency.
