摘　　要：网格技术作为一种新的计算范式正在兴起。网格论坛组织提出的OGSA(Open Grid Services Architecture)正成为网格应用的通用和标准化的体系结构,其核心就是网格服务,它是Web Service和网格技术的结合。开放网格服务结构(OGSA)定义了一类专门用于实现创建新网格服务实例的接口———Factory,并提供了在网格服务中创建、管理和交换信息的机制。伴随着Web Services技术中安全规范的制定,OGSA安全的标准化工作正在进行。文中介绍了Web Services和OGSA的基本结构,分析了OGSA中安全规范的制定情况,为OGSA研究和实施人员提供了安全规范的初步参考。As a new paradigm, grid computing （computational grid ）is springing up. OGSA （open grid services architecture）proposed by Global Grid Forum is becoming a common and standard architecture for grid-based applications. Grid service formed from Web service and grid technique is the key issue. OGSA defined an exclusively used for the realization to establish the solid example of new mesh service connection - Factory, and provided to establish in mesh serve, management and exchange the information of mechaniem. Standardization for security in OGSA is progressing with the development of Web services technology standardization. At first, the basic structure of OGSA is introduced in this paper. Then the instance of standardization for security in OGSA is analyzed. This paper intends to give a reference to security standardization for research of OGSA.
