摘要
介绍了基于分拆数的权限管理策略的原理及其在角色访问控制模型中的应用,实现了一个结构简单、伸缩性好、功能强大的权限管理系统。提出了自然数按集合分拆的新概念,同时给出了一个自然数按某个有限集狭义分拆唯一的充分条件。
This paper introduces the principle of authority system strategy based on partition number and its application in role-based access control models. Using this principle,a structure-simple,scaleable and powerful user-privilege management system is easy to be established.It also presents a new conception that a natural number is partitioned according to a set. Finally,a sufficient condition that a natural number is partitioned exclusively in a narrow sense according to a finite set is given.
