基于RBAC设计安全系统的面向方面

随着安全政策模型的进化，设计安全系统使用的模型也变得越来越复杂，亟须一种适用于管理开发、重用及设计的演化的方法。针对这种情况，基于角色的访问控制技术，采用AspectJ的组件规则和为设计提供扩展的UML设计符号的方法，提出了面向方面的方法设计安全系统。该方法易于学习和应用，且不必依赖特殊的实现模式。

RBAC-based design of user aspect-orientation of security systems

With the evolution of a security policy model comes the development of increasingly complicated models for the design of security systems. This results in a pressing need for a new approach geared to the development, reuse and evolution of the design. The solution involves the use of the composition rules of AspectJ and an extended UML design notation for the design. The paper proposes an aspect-oriented design approach to designing security systems. The approach offers an easier access and application and shows no dependence on a specific implementation model.
