| 摘 要： | 针对现有访问控制模型不能满足工作流系统安全需求的情况,本文设计一种基于角色和任务的工作流多约束访问授权控制模型(MC-TRBWAC),该模型采用动态授权机制和赋予多种细粒度的约束给用户、角色、任务和会话,减少了管理员的负担,避免了一些潜在的安全隐患,很好地满足了工作流系统的访问控制需求,使企业的授权管理更加灵活和安全。

| Abstract: | According to the case that the existing access control models can not meet the demands of the workflow system's security,this paper designs a task-role based workflow access control model with multi-constraints(MC-TRBWAC).Because of adopting dynamic authorization mechanism with multiple fine-grained constraints imposed on users,roles,tasks and sessions,it reduces the administrator's burdens,avoids some potential safety hazards,well meets the workflow system's access control requirements and makes the enterp... |
