一种改进的椭圆曲线数字签名方案

Digital Signature Scheme of an Improved Elliptic Curve

针对ECDSA多出存在耗时的求逆运算,重新构造签名和验证方程,提出了一个无需求逆的数字签名方案,并对该方案的正确性、安全性和性能进行了分析。分析表明,新方案是正确、安全的,而且具有运算量较小、运算速度较快的特点。

The signature and verification process of ECDSA （ Elliptic Curve Digital Signature Algorithm） was described in this article. Focused on more time - consuming inverse operation for ECDSA, the signature and verification equation were reconstructed, one digital signature scheme without inverse operation was presented, and the correctness, security and performance of the scheme were analyzed. The result shows that the new scheme is correct, safe, and it has features of low computational complexity and fast operating speed.
