| 摘 要： | 分析了椭圆曲线密码体制的安全性基础以及常见的攻击方法.考虑到目前还没有有效的方法可以求解有限域上阶中含有大素因子的非超奇异椭圆曲线的离散对数问题,指出高安全性的椭圆曲线密码体制可以靠选择有限域上高安全性的椭圆曲线来获得.给出了适于构建密码体制的椭圆曲线的构造方法.

| Abstract: | The security basis of the elliptic curve crypto system is analyzed. It is found that there is no efficient method to solve the discrete logarithm problem of non-supersingular with big prime factor over finite field. The high security elliptic curve cryptosystem is constructed by select the appropriate selection of high security elliptic curve over finite field. |
