I have to implement an rbac in mica motes. I've read that Xacml helps in implementation of rbac. But I searched tutorials and google and I'm not able to find anything relevant.Can some one please explain how it should be done or any lead to references.

Thanks

该博客将帮助您了解 xacml [1]。您可以从此处 [2] [3] 找到已使用 rbac 用例的 xacml 示例。实际上在 XACML 中，abac 和 rabc 都可以实现，这取决于您如何定义 xacml 策略。在您的策略中，您可以定义角色“bar”可以读取的“foo”资源。但实际上您想检查用户“bob”的授权。然后必须有一个 PIP [4] 在哪里，它有助于找到“鲍勃”的角色。
