| 摘 要： | 基于二叉树的分布式密钥管理体系分为单个密钥中心下的密钥管理系统和多层二叉树密钥管理系统．本文给出了两种管理系统下的用户密钥生成算法以及用户间秘密通信协议的实现过程，并且对公开密钥码的安全性进行了理论分析．基于二叉树的分布式密钥管理系统实现了既分散又集中的管理方法，最大特点是每个密钥中心只需存储唯一的一个秘密密钥，而且安全性也得到相应提高。

| Abstract: | The distributed key management system based on binary tree is divided into the key management system of one key center and the key management system of multi - layer binary tree. This paper presents the user with key production algorithm of the two kinds of management systems and the realization process of secret communication protocol between users. A theoretic analysis is made on the security of public key code. The distributed key management system based on binary tree has brought about both decentralized and centralized management. Its most prominent characteristic is that each key center needs only one secret key and its security can be improved accordingly. |
