摘要
本文论述了如何在工作流系统中实现存取控制的问题。用形式化的方法阐述各种模型的特性 ,以工作流系统的安全需求为背景 ,对各种模型进行了比较。最后 。
In this paper,we solve the problem how to integrate access control service into work flow systems.Several access control models are introduced by formalized definition.And their features are compared based on the security requirement of work flow systems.The existing problem of current model and future research direction is discussed in the end.
