摘　　要：提出了一种基于椭圆曲线密码系统的组合公钥技术。组合公钥技术将一定数量的私钥因子和公钥因子组成私钥因子矩阵和公钥因子矩阵,并通过映射算法和组合因子矩阵分别计算出用户的公钥和私钥,试图解决大型专用网中大规模密钥管理的难题。The Combined Public Key technique based on elliptic curve cryptography is proposed in this paper.In Combined Public Key technique,private key factor matrix and public key factor matrix are constructed,and the private key and public key of users can be computed through the private /public key factor matrices and a given mapping algorithm.This method is intended to solve the problem of large-scale key management in private networks.
