摘要
基于椭圆曲线离散对数问题(ECDLP)和平方剩余问题,本文提出了一种新的具备消息自动恢复特性的数字签名方案,同时对该方案进行了各种安全性分析,得出结论:该方案具有前向安全性,而且在第三方仲裁时无需泄露密钥(即具有零知识特性).
Based on both ECDLP and quadratic residue problem, in this paper, we present a new signature scheme with message recovery. We also analyze the security of the new scheme and conclude that the scheme satisfies forward security. In a case of dispute, both the sender and the receiver can convince arbiters whether the signature is valid or not without revealing their secret keys.
