摘　　要：分析了访问控制领域研究的现状,讨论了协同设计系统应用中访问控制的特点。针对协同设计系统中访问控制技术不断提出的新需求,将传统的基于角色访问控制模型改进为混合扩展模型(HRBAC),主要是在RBAC96模型基础上加入了分组和代理的概念。给出了扩展模型的形式化定义,讨论了引入新元素后的模型特点。改进后的模型可以简化协同设计系统中访问控制管理的复杂性,并能够满足企业间访问控制的交互需求。The current research in access control is analyzed, and the features of access control in collaborative design systems are discussed. According to the new requirements of the access control technology in collaborative design systems, the traditional model Of role based access control is improved to a new one： Hybrid extend role based access control model. The improvement adds the concept of division and delegation to the model RBAC96. The formal definition of the improved model and the features of the newly-introduced model elements are also given and discussed. The improved model can simplify the management of the access control in collaborative design systems, and is more suitable for the demand of the interaction between the enterprises.
