基于XACML的RBAC模型的研究与应用

RBAC（Role Based Access Control基于角色的访问控制）模型作为访问控制系统中的理想选择。近年来得到了广泛的研究。本文针对规模较大的访问系统的特点。提出一种改进的基于XACML的访问控制模型，使得RBAC模型具有了良好的灵活性、扩展性、以及跨平台性，并将该模型在大型互动网络游戏开发平台中进行了验证。

Research and Application of XACML Based on RBAC Model

As an ideal choice in computer supported cooperative work system,role based access control has been studied by many researchers. And improvements have been proposed to perfect it in recent years. This paper proposes a new improved access control model based XACML to fit for the system, it makes the access control more flexible and safer, and has been validated on largescale interactive online game platform.
