摘　　要：采用Java提供的大数操作,对素数域上椭圆曲线进行深入分析,以国际上相关的研究和算法实现工作为基础,采用数学建模和面向对象的思想,根据椭圆曲线密码体制,实现素数域椭圆曲线加密系统,给出详细的设计,并分析了其中的关键算法。针对Java在网络上的广泛应用,将其应用于网络验证,保护网络应用系统的安全。The elliptic curve over prime finite field is analyzed deeply by using big integer provided by Java. Using mathematics modeling and object oriented method, according to EC public key encrypt theme, the elliptic curve encrypt system over prime finite field is achieved based on international relevant research and algorithms. Some important algorithms and detailed design of the system is proposed. In view of the wide application of Java in network, this cryptosystem is applied to network authentication for protecting the security of the system information.
