基于椭圆曲线的XML数字签名研究与实现

Research and Implementation of XML Digital Signature Based on Elliptic Curve

在分析基于椭圆曲线的XML数字签名流程及其安全性的基础上,改进影响椭圆曲线签名算法(ECDSA)实现效率的关键模块,提高其整体运算效率,实现了基于椭圆曲线的XML签名服务。在统一平台上对三种公钥密码服务实现XML数字签名的性能进行比较,实验结果表明,在XML签名中使用ECDSA,能够实现网络环境中高安全性、高效率的数字签名处理。

By the analysis of XML digital signature based on elliptic curve and its security, an XML digital signature service based on elliptic curve is proposed and implemented, through optimizing the key algorithm of elliptic curve digital signature algorithm （ECDSA）, which has effected the whole implementation efficiency. Compared with the performances of XML digital signature schemes based on another two public key cryptographies on a uniform platform, the result of the experiment shows that the scheme based on ECDSA is more secure and more efficient to deal with signature in the network environment.
