| 摘 要： | 文章以近几年公钥密码学研究的热点椭圆曲线密码体制为例。说明密钥数据的结构及其存储问题。所设计的公钥密码系统是一个开放式系统。在用户终端建立私钥库PrKD和公钥库PuKD，产生各种密钥。同时完成数据加解密、签名及验证功能；在密钥服务器上建立一个公钥库SevD，存放密码系统中所有用户的公钥信息。为用户提供公钥发布和交换功能。按照不同的安全性要求，PrKD中的数据要求完全保密。SevD的数据要求防止篡改。

| Abstract: | This passage is takes to key-Elliptic curve system for example, which is the hot point of the Public-key Cryptosystem during the recent years. So as to illustrate the structure and store problem of the Key Date. The designed Public-key Cryptosystem is an open-system. It establishes the PrkD and pukD at the user terminal,and at the same time produces various key. Fulfills the encrypt and deciphering, signs, and verifies functions; to establish a SevD in order to store all the Public-key information. Provide the Public-key declaration and exchange ability for the users. According to the different requests on securing.the dare of PrkD will be kept secretty completely. And as well as avoiding distorting. |
