摘要： 拒绝服务(DoS)攻击对分布式应用系统的安全威胁日益严重。文章提出了一种基于移动Agent的分布式应用系统架构,用以保护系统中的应用服务器,提高其抗DoS攻击的能力。为进一步改善系统抗DoS攻击性能,提出了一种基于遗传算法的代理主机分组算法。最后定性评估了系统的抗DoS攻击能力。

Abstract: The denial of service(DoS) attack is becoming a serious threat to the distributed application system.A mobile agent-based architecture for the distributed application system is presented.The architecture can protect the application server and improve its DoS resistant ability.To be more secure in the case of DoS attacks,a proxy host grouping method based on the generic algorithm is presented.In the end,the DoS resistant ability of the system is analyzed.
