摘要
工作流技术是生产与办公提高效率的有效办法,然而工作流系统的安全问题却没有得到很好的解决。通过研究RBAC安全访问与控制技术的优缺点,结合工作流系统的安全需求,提出一种基于任务机制的RBAC模型。该模型引入任务群管理机制,通过任务的动态授权,实现对角色访问权限约束,消除角色最小权限约束假象,提高工作流的安全性能。
Workflow technology is the production and office effective way to improve efficiency,but the security of the workflow systems has not been satisfactorily resolved.By studying security access and control of RBAC and the security requirements of workflow system,proposed a RBAC model based on task mechanism.The model introduces the task mechanism through the dynamics of the task authorization,and eliminates the illusion on least privilege constraints.and improves the safety performance of the workflow.
