基于AES算法的移动IPv6绑定更新信息处理效率分析

The Efficiency Analysis of Disposing Binding Update/Acknowledgement Messages in Mobile IPv6 Based on AES Algorithm

移动 IPv6中移动节点向家乡代理和通讯对端告知自己当前位置而传输的信息是通过绑定更新(Binding Up-date)来进行的,绑定更新的过程通过移动节点的注册来完成。家乡代理处理绑定更新信息的性能和效率对尽快定位移动节点的位置是一个比较关键的问题,尤其是在移动节点数量多、移动频繁及考虑信息加密的情况下,问题显得更为突出。IPv6在这方面还需要做进一步的研究和改进。本文提出了移动 IPv6中绑定更新信息数量统计的数学模型,并在该数学模型的基础上,首次提出将 AFS 算法应用于该类信息的处理,并与其它处理方法做了比较。

In mobile IPv6, MN communicates with HA and correspondent nodes by Binding Update/Acknowledgement messages for locating its current position. The Binding Update/Acknowledgement proceeding is achieved by the MN registration. For quickly locating a MN, HA disposing efficiency is a key issue, especially under the condition that MN is excessive and it＇s moving is frequent. In mobile IPv6, it is necessary to improve the efficiency of HA disposing Binding Update/Acknowledgement messages. In this paper, the amount of Binding Update/Acknowledgement message mathematic model is proposed and AES algorithm is employed to encrypt/deerypt Binding Update/Acknowledgement messages firstly in mobile IPv6.
