摘要
介绍了AAA服务体系以及基于AAA的移动IP注册过程,提出了在这种情况下功能实体间的安全关联更新方案,从而避免了因为过长时间使用相同的密钥信息可能导致的攻击.
This paper introduces the AAA infrastructure,analyzes the authentication process and registration process in Mobile IP based on AAA.Then we propose a new method to fresh the security association between each functional entities involved in the infrastructure on the basis of that.This arithmetic can avoid attack which probably caused by using the same secret key for a long time.
