| 摘 要： | 针对CSCW(computer supported cooperative work)中的访问控制需求,利用基于角色和基于任务的访问控制技术,将协同设计中的用户、任务、角色、权限相关联,并引入属性证书进行授权,建立了一种新的访问控制模型NT-RBAC(new task-role based access control),并实现了基于该模型的访问控制子系统。实例表明NT-RBAC提高了CSCW中访问控制的灵活性和安全性。

| Abstract: | According to the requirement of access control in CSCW(computer supported cooperative work),a new access control model NT-RBAC was constructed with the technology of access control based on role and task.The model asso- ciated users with task,role and permission in collaborative design.Meanwhile the attribute certificate was introduced to authorize permissions.Finally,an access control system based on this model was implemented,and instances show that the proposed system can improve the agility and security of the access control effectively. |
