【摘要】 本文对椭圆曲线密码体制进行了概述与研究,并对椭圆曲线的原理、群的构成、对数问题、“倍点”公式以及城上元素运算的实现等一系列问题进行了讨论。最后,介绍了在椭圆曲线支持下的公开密钥密码体制。更多还原

【Abstract】 In this paper,we analysis Elliptic curve cryptosystem briefly,and discuss the principle of elliptic curve,group make-up alogarithm problem,"double-point" problem and the implement of the field elements’ arithmetic etc.At last,introduce the public-key cryptography support by the elliptic curve.更多还原
