摘要
基于企业网格具有多层次,多任务,多用户以及需要对不同访问采取不同的权限限制等特点,该文提出了一种采用工作流安全认证模型。在网格环境中,任务执行时需要有特定权限,如果赋予权限不够,则不足以完成任务;如果赋予权限过大,对企业安全又起到了威胁。因此该模型在执行一个任务的过程中,针对不同种类的企业客户及不同的授权任务指定一个适当的具体权限,从而确保任务安全,高效的完成。
An workflow safety authorization service model is proposed, because enterprise grid has characteristics of multi-tier and multiuser and different right limitation for different user at different stage.In the grid environment, when a task is carried out it needs specific right.If delegated rights are insufficient, the task cannot be complete;if delegated rights are excessive, it maybe bring security threats for enterprise safety.wherefore when a task is executed, this model designate a specific right for different enterprise user and different authorization task.Insure the task to be completed safely and efficiently.
