网格工作流访问控制研究

工作流管理系统中采用适当的访问控制机制能够确保各项任务被合法的用户或代表一定用户利益的合法程序执行。本文对网格工作流访问控制做一些非形式化研究,提出了基于服务的网格工作流动态访问控制模型,将工作流中任务和服务相联系,实现了工作流中访问控制的最小特权原则。

Researcher on Grid Workflow Access Control

Workflow management system,the adoption of appropriate access control mechanisms to ensure that all tasks are a legitimate user or on behalf of the legitimate interests of a certain user program execution.In this paper,grid workflow access control to do some non-formal studies,proposed service-based grid workflow dynamic access control model,the workflow tasks and services linked to achieve the workflow in the principle of least privilege access control.
