摘要
简要介绍了椭圆曲线及其上有理点组成的Ａｂｅｌ群，讨论了椭圆曲线上的几个公钥密码体制，这些体制的安全性至少与有限域上相应体制的安全性是一样的，而实现的速度却更快。
The Elliptic curve and the Abel group composed of rational points on the elliptic curves are introduced,and some of the public key cryptosystems on the elliptic curves are discussed.These have at least the same safety as the relavant systems of rational fields,and their obtaining speed is faster.
