摘　　要：由于椭圆曲线密码体制具有长度小、安全性高的特性,因此,椭圆曲线在安全保密方面得到了广泛的应用。椭圆曲线参数的选取会影响椭圆曲线的难解程度,从而影响到系统的安全性。本文主要通过PSO粒子群算法查找函数最优解的方法来优化选择椭圆曲线的参数,从而得到安全的椭圆曲线,实验表明该粒子群算法具有很强的实用性。With the feature of short length and high security, the elliptic curve has been widely used in cryptosystem.We select the parameters which will have a certain impact on the answer of the elliptic curve and lead to influence the system’s safe.Therefore, this paper uses the Pso algorithm to find the parameters of the elliptic curve by the method of finding the optimal solution for function.Thus, the secure elliptic curve is achieved, and experiments show that the usefulness of particle swarm algorithm.
