移动IP拒绝服务的防御

移动IP的引入为解决终端的移动性接入问题，因其存在无线链路和有线链路2部分，使得入侵者不但可以在有线网络部分进行攻击还可以通过无线方式发起攻击。在无线链路上，黑客可以不直接接入网络就可以发起攻击，且加之无线频带资源的有限，若在无线链路上发起DoS(denial of service)攻击必将带来很大的危害性。分析了移动IP中DoS攻击的原理和表现方式，提出了解决移动IP中的DoS的方法。

Defence against DoS for Mobile IP

Mobile IP is introduced for solving mobility access of terminals.Because mobile IP communicatuion is through both wireless links and wired links, attackers may not only attack network in wired part of it ,but also through wireless way.For wireless link,hacker can make an attack on network without directly getting access to it ,and because of the limitation of frequency band resouce,if a DoS attack is made in wireless link,great harm will certainly be brought. In this paper,the principle and manifestation of DoS attack in mobile IP are analysed,and the methed for solving DoS attack in mobile IP is presented.
