一个扩展的CAM协议

An Extended CAM Protocol

随着IPv6技术的稳步发展以及移动IPv4面临移动性、安全性差等越来越多的问题,移动IPv6由于取优良的性能而日益引起人们的关注。如何防止绑定更新消息遭受攻击是移动IPv6在开放式环境中面临的难题。本文针对CAM协议的不足提出了一个扩展的CAM协议。该协议实现了协议双方的相互认证并能抗DOS攻击。最后对该协议的安全性和功能进行了分析与论证。

With development of IPv6 and mobile IPv4 being faced with more and more difficulties mobile IPv6 isattractive because its nice performance. How to protect binding update messages to defend against attacks is achallenging problem given the open environment in which MIPv6 operates. This paper presents an extended CAMprotocol aimed at overcome the shortcomings of CAM protocol. This protocol can realize mutual authentications ofits two sides and resist DOS attack. Finally, the author demonstrates the security and function of this protocol.
