Research on the Digital Signature Technology on the basis of Improved Elliptic Curve

椭圆曲线密码(ECC)是目前最流行的公钥密码体制,而椭圆曲线数字签名(ECDSA)是公钥签名体制在椭圆曲线密码体制中的重要应用。本文针对椭圆曲线数字签名算法(ECDSA)计算复杂度高,提出了一种改进的数字签名方案,并对其安全性进行了简单的分析。

Elliptic Curve Cryptography（ECC） is currently the most popular public key cryptosystem and elliptic curve digital signature（ECDSA） is the important applications of a public-key signature system in the elliptic curve cryptosystem.In this paper,an improved digital signature scheme is proposed and its security is analyzed,according to the high computational complexity of Elliptic Curve Digital Signature Algorithm（ECDSA）.
