摘要：

随着网络的迅速发展,电子选举已经成为了电子政务的一个重要应用方面。但电子选举具有海量数据和实时性的特点,并且对安全要求高,而椭圆曲线密码算法具有安全性更高、计算量小和处理速度快、存储空间占用少、带宽要求低的优点,这就势必要用椭圆曲线密码算法来取代原电子选举系统的身份认证和选票验证阶段。因此,文章提出了一种基于椭圆曲线的数字签名算法,并且将其应用用于电子选举系统,从而提高了电子选举系统的安全性。

Abstract: With the development of network,E-voting became the important means of e-government.Electronic election has characteristic of being magnanimous data and real time and requesting high safety.Elliptic curve secret cipher algorithm has just the superiority:security is higher,computation quantity is small,processing speed is fast and storage space is small.It also has few requests on band width.It is easy to see that elliptic curve algorithm will take place of other algorithms.This article proposed one kind algorithm based on elliptic curve and used it in the E-voting system,thus enhanced the E-voting system's security.
