Abstract:
As a way to defend information’s confidentiality and integrity, access control takes a quite important role in military system and commercial system. Workflow is splitted into several task units, and the inter relationship among tasks is formally described. This paper gives startup condition of the task instance, puts forward a new access control model based on task. Experimental results show that the model is effective.
Key words:
access control,
confidentiality,
integrity
摘要: 作为保护信息资源机密性和完整性的重要手段,访问控制在保密系统、商业系统中占据了重要地位。该文将工作流分解成若干任务单元,形式化地描述了任务间的相互关系,给出任务启动的条件,提出一种基于任务的访问控制模型。实验证明了该模型的有效性。
