摘要
P2P应用已经成为Internet上最流行和成功的应用之一,基于P2P的DDos攻击是国内外研究的重点。本文首先概述了BitTorre nt的协议原理运行过程,并用MTTrace工具采集和分析了Tracker服务器的节点集合的链路特征,发现节点集合的链路的拥塞链路特征,针对此特征本文设计了一种新的DDos攻击策略,并在模拟环境中对其进行了验证,然后我们对其防御手段进行了讨论,最后,我们对所做的工作进行了总结,并对下一步的工作进行了说明。
BitTorrent have become one of the most popular and successful applications on the Internet.DDos attack based on P2P is one of the important research perspectives.This article first introduce the structure of BitTorrent and its runtime process.And then we use MTTrace collection the links of nodes in the Tracker server,and analysis the links we found the links data which has congestion have a feature.Using the feature,this article design a new policy of DDos attack,and evaluate it in the simulation.Finally,we discuss the further direction of P2P-based attacks and its defense mechanism form the view of promoting the safety of P2P network and Internet.
