Modeling,Implementation and Application of Extensible Access Control
可扩展存取控制建模、实现与应用

Effective control of access for resource is key to make users work collaboratively.It is also important to ensure information security.Having analyzed traditional access control technologies,a new access control model,eXtensible Access Control Model (XACM),is proposed in this paper.An extensible access control system based on XACM is successfully implemented for control of access to information in Tongda Group's workflow-based office automation system.It proves the characteristics of XACM such as flexibility and generalization.
