摘要
介绍了椭圆曲线加密机制和数字签名技术的原理,通过对椭圆曲线加密和数字签名算法的分析,提出了一种基于ECC加密算法的数字签名方案,其安全性是基于求解椭圆曲线离散对数问题的,可在保持与RSA或DSA体制同样的安全性的前提下缩短密钥长度、降低通信成本、提高网络信息的安全性。
This paper introduces the technique of digital signature and analyzes the technique of crytosystems and digital signature,then presents a digital signature scheme based on ECC.Its security bases on solving the elliptic curves cryptosystems discrete logarithm problem.It can keep with RSA or DSA the premise of equally safe functions in systems descend to shorten the length of key and have lower communication costs than RSA or DSA and therefore the schemes lowered the communication costs and increases the safety of the network information.
