摘要
介绍了基于Petri网工作流的动态访问控制的概念。文中描述的方法可把访问控制矩阵从二维扩展到三维,并使之动态化,从而降低数据滥用的风险。
This paper introduces the conception of dynamic access control, which is based on Petri Net Workflows .The approach described in the paper can extend access control matrix from two to three dimensions and make it dynamic .Thereby, the risk of data misuse is decreased .
