摘要： 基于异地制造系统的信息流动特点,在传统的访问控制矩阵基础上,提出了一种基于Petri网工作流的动态访问控制策略,给出了其访问规则和矩阵形式,并以一个方案评审工作流系统为例,说明了该方法的应用.

关键词: 动态访问控制, Petri网, 协同工作, 工作流

Abstract: The traditional access control mechanism in a distributed cooperative work system is static and lacks flexibility. So a new access control method called dynamic access control is introduced here. It combines the workflow management with access control matrix to improve the flexibility and efficiency. How access rights can be derived from a Petri net workflow is discussed in this paper. Access rights are granted according to the state of the workflow. The concept of workflow is defined by Petri nets which offer a solid mathematical foundation. Finally the method is implemented in a collaborative project discussion process of a cooperative work system called eCWS.

Key words: workflow, Petri net, cooperative work, dynamic access control
