摘　　要：随着网络的普及与信息技术的发展,数字证书系统成为保证信息安全的重要工具。但数字证书系统所涉及的方面众多,结构复杂,开发难度大。SysML(Systems Modeling Language)是系统工程应用开发的标准建模语言,为系统开发者提供了统一、表达力强、可视化的系统工程描述方法。本文通过使用SysML的各种视图,对系统的组成、接口与通信关系、系统功能、状态转移进行描述,可以有效降低系统的设计难度,提高设计效率,便于后期系统的优化与实现。同时对于其它相类似的复杂大系统的设计有指导意义。Because of the popularization of the network and the development of the information techno-logy,the Digital Certification System becomes the significant instrument which protects the security.But the Digital Certification System has multitudinous apartment,complicated configuration,so it is hard to design.SysML（System Modeling Language） is a standard modeling language for systems engineering application,provides an uniform、 expressively and visual system engineering description method for the system developers.By using various diagrams of SysML to describe the composing,interface,com-munication,function,state transition of the system,it reduces the difficulty of and increases the efficiency of designing,makes the optimization and implement easily in flowing work.At one time,it provides directions for the designing of the other similar large complex system.
