Mogent防DoS攻击的策略与实现

Defense Against DoS Attack in Mogent System

随着对移动Agent技术的研究和应用不断深入 ,移动Agent系统的安全问题越来越受到关注 .在诸多类型的安全问题中 ,DoS攻击作为一种常见的攻击手段 ,其危害性尤为突出 .本文介绍了移动Agent系统中两种基本的DoS攻击的形式 ,通过分析它们各自的机理 ,分别提出防御策略 ,最后介绍了南京大学计算机软件新技术国家重点实验室自行研制的Mogent系统中对此策略的实现 .

With the development of Mobile Agent technology and its application, more and more attentions are paid to the security issues in mobile agent system. As a frequent attacking instrumentality, DoS attack is especially harmful. This paper introduces two basic means of DoS attack in mobile agent system, analyses their principles and proposes the defense strategies against them respectively. In addition, we also introduce the implementations of these two strategies in Mogent (Mobile Agent) System.
