摘要
椭圆曲线密码体制以良好的安全性,曲线选择范围广,在同等长度的密钥下具有比RSA体制更快的加、解密速度及更高的密码强度等优点而得到广泛应用。椭圆曲线数字签名实际上是数字签名在这种密码体制下椭圆曲线上的模拟。文中提出了一种基于椭圆曲线数字签名算法的软件序列码生成和验证方案,实践证明这种方案具有较高的安全性,在实际应用中是可行的。
Elliptic Curve Cryptosystem is widely used because it has many advantages such as a high security, a wide range of curve selection, a quicker speed in encryption and decryption, and higher cryptogrammic intensity than RSA under the same length cipher key. Actually, Elliptic Curve Digital Signature is a simulation of the digital signature on the elliptic curve under this cryptosystem. In this paper, a software serial number creation and verification method based on Elliptic Curve Digital Signature Algorithm is shown, and the security and feasibility of this method has been proved in practice.
