Research and application of dynamic access controls 动态访问控制技术的研究与应用
The protocol the author designed for superpon , provides half - static and demand dynamic access control method according to different delay requirements 作者设计的协议中,根据不同时延要求,提供半静态和动态的带宽分配方法,满足不同业务的需求。
However , rbac and grbac are difficult to meet dynamic access control requirements because they are essentially established on the static subject - object view 然而, rbac和grbac本质上是建立在静态的主体-客体访问控制思想之上的,难以满足动态访问控制的要求。
In addition , the database can have a better understanding of the state of the data it stores , and thereby can produce a more efficient and dynamic access path to the data 此外,数据库可以更好地理解它存储的数据的状态,从而可以生成到数据的更有效和动态的存取路径。
The work has improved rbac on the capability of dynamic access control , and can be used for reference by their practical application , especially in distributed environment 本文的研究工作改善了rbac和grbac的动态访问控制能力,为rbac和grbac在分布式环境下的应用提供了有用的参考。
