混合角色访问控制模型在CSCW中的应用研究

The application of CSCW by mixed role and task access control models

CSCW技术的研究已经受到人们的广泛重视,随着该项技术逐步应用到实际的生产应用领域,人们越来越关注其安全性的研究,其中的一个热点问题就是访问控制技术的研究。本文分析了著名的基于角色的访问控制模型(RBAC)和基于任务的访问控制模型(TBAC)的不足,提出了一种基于重复角色和任务优先级的访问控制模型(RR-TPBAC),并开发了一个计算机协同管理系统。

CSCW technology research has been the extensive attention of the people, with the gradual application of the technology to practical production applications, there is growing concern about their safety studies, one of the hot issues is the access control tech- nology research. This paper analyses the well-known role-based access control model （RBAC） and task-based access control model （TBAC）,access Control Models Based on Repeated-Role and Task Priority （RR-TPBAC）, and the development of Collaborative management of a computer system.
