摘要
基于文件血统的访问控制机制是近年来提出的一种全新的控制思路与方法,本文是在此基础上,提出了基于血统机制的文件模型。主要描述了模型的定义,结构,约束条件,以及血统的验证过程,最后详细介绍和讨论了该模型的实现方法。
The access control based on file lineage mechanism is a new ideas and method in recent years, and a file lineage model is presented. This paper mainly describes the definition of lineage, the structure of model, the constraint condition, and the verification process of lineage relationship. Detailed discussion is given regarding the implementation of models based on file lineage mechanism.
