| 摘 要： | 针对传统的基于角色的访问控制模型的不足，给出了一种基于角色的代理访问控制模型，将上下文、观察者和代理的概念引入到了访问控制中。该模型能够根据上下文环境的变化而动态地做出访问决策，访问控制检查也不需要放入业务逻辑实现的代码中，而是由观察者观察业务逻辑执行情况，当需要访问控制检查时通知代理主体，由代理主体做出访问控制决策。这种模型可以很好地在Spring AOP框架中实现。

| Abstract: | This paper has analyzed the shortcoming of the traditional role-based access control(RBAC) model and given a new one called the role-based agent access control(RBAAC) model.In this model,some concepts of context,agent and observer are introduced.This model can make decisions of access control dynamically according to the change of context.The checking of access control can be made by agents.When the checking is needed,the observer will find it and inform the agent.The model can be well realized in the frame... |
