多级安全工作流授权模型

Authorization model for multilevel security workflow

论述了用于工作流管理系统中的工作流授权模型 .针对工作流在多级安全环境下的应用 ,提出了一种多级安全工作流授权模型 .模型增加了安全级及任务相关性的表示 ,对原模型的授权规则进行了改造 .提出了判断可达性的算法 。

This paper briefly describes the workflow authorization model for workflow management system, and presents authorization model for a multilevel security workflow in the multilevel secure environments. The model adds the presentation of security level and task dependence and reforms the authorization rule for the improved model. An algorithm to detect the accessibilities of terminal nodes is also put forward.
