集成AAA的HMIPv6认证与注册方案

A scheme for Authentication and Registration in the HMIPv6 Integrated with AAA

在下一代互联网中,需要使用AAA保证网络安全和网络资源合理使用,但是AAA与移动IPv6的结合,对切换性能及网络安全带来影响,而切换与安全是移动环境的关键问题。论文提出了新的解决方案,将HMIPv6与AAA结合,实现认证与注册过程的统一及本地认证,提高切换性能,并在注册与认证的过程中对消息进行加密,保证传输的安全。分析表明,本方案实现了AAA机制与移动管理机制安全高效的融合。

AAA system is the important security infrastructure for Mobile IPv6 networks. However, integrating AAA with Mobile IPv6 networks may degrade handoff performance and the security of networks. And mobility handoff is the key problem in mobility environment. In this paper, we propose a new scheme to integrate AAA into Hierarchical Mobile IPv6 （HMIPv6）. AAA authentication and mobility registration are performed together with the sequential registration, and could be handled locally in intra-domain handoff cases. In addition, key operations are employed simultaneously to ensure the secure transmission and authentication of data. Final analysis shows that this new scheme is secure and efficient for integrating AAA into HMIPv6 networks.
