本文以PKIX 标准作为PKI 的建设规范,在分析PKI 需求的特点和构建需求模型的常用模式的基础上,提出使用UML 的构件、参与者和用例三个概念为主体构建PKI 需求模型,然后分析PKIX 标准,定义出PKI 需求模型所应当包含的构件、参与者和用例,最后确定PKI 需求模型各个单元之间的关系,从部署和构件组合图、用例图和序列图三个视角实现PKI 需求模型。关键字:PKI;UML;建模;需求Abstract: This paper takes PKIX as the norm of PKI. By analyzing the peculiarity of PKI and the general mode of building requirement Model, we present using component, actor and use-case to build PKI requirement model. Then, we analyzed PKIX and make use of component, actor and use-case to construct PKI requirement model.The PKI requirement model include deploy and component diagram, use case diagram and sequence diagram.Key words:PKI;UML;Model;Requirement
