可动态更新密钥的Mobile IP安全注册协议研究

Research of Secure Registration Protocol with Dynamic Updatable Key for Mobile IP

在MobileIP中,注册与认证是一个关键因素。对MobileIP注册中的安全性进行了研究,提出了一种以对称式加密算法为基础,以Nonce来达到相互认证同时可以动态变换通信双方会话密钥的安全注册协议。最后,对此协议的安全性进行了分析。

Authentication and registration in the mobile IP is the key for the Mobile IP to proceed.By the study of securities in registration,this paper presents a suit of secure registration protocol based on symmetrical encrypt arithmetic and authenticates one another with Nonce.At the same time,it can transform dynamically the session key of both sides in communication.Furthermore,the securities of the registration protocol are discussed.
