摘要:
现有的代理数字签名方案都是基于离散对数问题和大数因子分解问题的方案。文中提出的数字签名方案的思想包括签名方案的前向安全性、代理签名的不可抵赖性。该方法是一种基于椭圆曲线离散对数问题的代理签名方案。文中对方案的复杂性和安全性进行了分析，分析结果表明该方法安全可行，同时也扩展了椭圆曲线密码的密码功能
Abstract:
The present representative digital signature approaches are based on discrete logarithm problem and large number factor decomposition. The idea of the digital signature approaeh proposed in this paper includes the forward security and nonrefutation of representative signature. The approach is based on elliptic curve discrete logarithm problem. The paper made an analysis on the complexity and security of the proposed signature approach. The analytical result shows that the approach is safe and feasible, and it extends the cipher function of elliptic curve codes
