摘要
数据加密、数字签名方案是保障通讯数据真实可靠的关键。文中提出了一个基于环Zn上圆锥曲线公钥密码体系的新型数字签名方案,并给出了该数字签名方案的数值模拟。该方案综合利用了大数分解的困难性和有限群上计算离散对数的困难性,从而增强了该数字签名方案的安全性。
The digital signature scheme is designed on the basis of Public-Key Cryptography on Conic Curve over Zn, and the numeric simulation for the digital signature is given. The scheme makes full use of the difficulties in factorizing large integer and computing discrete logarithm, thus increasing the performance of security.
