基于MAPE结构的组播AAA模型

指出了现有组播协议存在的安全性问题，提出了一种基于MAPE的组播服务AAA模型，给出了该结构下的核心模块组播敏感第二层交换机的内部结构和工作原理，并阐明这种体系结构对于在城域网范围内开展有偿组播服务的重要意义。

A Multicast Service Model Based on MAPE

As link speed and device throughput are increasing rapidly in recent years, broadband service such as video-on-demand and remote education run all the way to commercialization. But the open characteristics of current multicast mechanism provide no means to ensure data secrecy and integrity. In this paper, we introduce a method to enhance multicast security and explain that application level authentication is not enough to ensure multicast security. Then we present our MAPE based multicast service AAA model. The structure of MAPE is introduced in detail, together with the messages exchanged between MAS and MuPS. We further explain that our scheme is flexible and scalable.
