最近，反P2P公司已经成功地减少了一些P2P文件共享系统上的目标内容的分发，包括Kazaa和eDonkey。最近，反P2P公司开始攻击BitTorrent。在本文中，我们分析了两种不同类型的攻击：连接攻击和片段攻击的BitTorrent水蛭的弹性。我们提出了被动和主动测量的结果。使用被动测量，我们对最近受到攻击的专辑进行了详细分析，并确定了攻击者的行为。对于我们的主动测量，我们开发了一个爬虫，它可以联系任何给定群中的所有对等体，确定群是否受到攻击，并识别群中的攻击对等体。我们使用爬虫分析了8部票房最高的电影。基于测量结果，我们发现BitTorrent架构从根本上抵御了Internet leecher攻击。最后，我们还提出了防御机制，以进一步减轻攻击，并使用跟踪驱动的模拟评估其有效性。
In the recent past, anti-P2P companies have successfully curtailed the distribution of targeted content over a number of P2P file-sharing systems, including Kazaa and eDonkey. More recently, anti-P2P companies have begun to attack BitTorrent. In this paper, we analyze the resilience of BitTorrent leechers to two different kinds of attacks: the connection attack and the piece attack. We present the results of both passive and active measurements. Using passive measurements, we performed a detailed analysis of a recent album that is under attack, and identified the behavior of attackers. For our active measurements, we developed a crawler that contacts all the peers in any given swarm, determines whether the swarm is under attack, and identifies the attack peers in the swarm. We used the crawler to analyze 8 top box-office movies. Based on the measurement results, we discovered that BitTorrent architecture is fundamentally resilient to Internet leecher attacks. Finally, we also propose defense mechanisms to further mitigate the attacks and evaluate their effectiveness using trace-driven simulation.
