基于P2P系统的DDoS攻击及其防御技术研究综述

Research on P2P-based DDoS attacks and their defense mechanism

首先概述了利用P2P系统进行DDoS攻击的原理,并根据攻击方式的不同将现有研究划分为主动攻击和被动攻击两种。综述了当前针对基于P2P的DDoS攻击的防御方法,分别从基于验证的方法、基于成员管理的方法、基于信誉的方法和受害者端的方法四个方面进行说明。最后,从推动P2P网络安全和Internet网络安全的角度出发,对基于P2P的DDoS攻击及其防御技术未来的研究方向进行了探讨。

This paper first introduced the principle of exploiting P2P systems to perform DDoS attacks,and then classified existing researches as two types： active attacks and passive attacks.Summarized the defense solutions and described them from four aspects： validation-based method,membership-based method,reputation-based method and victim method.Finally,discussed the further directions of P2P-based attacks and their defense mechanism from the view of promoting the safety of P2P network and Internet.
