基于复合状态的工作流授权

Research on composite status based workflow authorization

提出了一个新的工作流授权模型,目的是解决工作流的执行流和授权流不能同步的问题.新模型是基于工作流任务调度的授权系统.通过分析工作流授权状态和工作流任务执行状态之间的转换,将授权状态和执行状态进行绑定,提出了复合状态的概念.然后使用预授权操作和复合状态转换操作完成复合状态的转换,从任务调度的角度解决了工作流的执行流和授权流不能同步的问题.最后通过针对授权同步性能的测试验证了新模型能够使授权流和执行流同步的结论.

This paper presents a new workflow authorization model, which aims to solve the problem that execution flow and authorization flow of workflow system can not be synchronized.This new model is a workflow authorization system based on workflow task scheduling.By analyzing the transition between workflow authorization status and workflow task execution status,authorization status and task execution status are binded together.The concept of composite status was proposed.Then transfer and judge operation was used to transit composite status,which solves the problem that authorization flow and execution flow cannot be synchronized on behalf of workflow task scheduling.The above conclusion was validated,that the new model can make execution flow and authorization flow synchronous,through the test on capability of authorization synchronization.
