基于角色的CSC W系统安全模型

The security model of CSCW system based on RBAC

针对计算机支持的协同系统用户多 ,权限关系复杂 ,组织机构规模大的特点 ,给出了基于角色的访问控制在CSCW中的安全模型 .该模型通过RBAC提供的安全策略和协同工作策略实现了CSCW系统的安全机制 .研究表明 ,该模型描述简单 ,易于管理 ,能很好地将RBAC和CSCW系统对安全和协同工作的需求结合起来 .

Aimed at the characteristics of CSCW systems involving a large number of users, complicated property relationship and large-scale organizations, a security model was presented based on RBAC theory. The model implemented the security mechanism of CSCW system according to security policy and cooperative policy provided by RBAC. It was shown that the model was easy to describe and manage, and could combine the RBAC with the security and cooperative requirements of CSCW system.
