对等（P2P）文件共享网络在过去几年中已经见证了急剧增长的普及。为了满足用户的需求，大多数P2P文件共享网络主要集中在提高传输效率和网络可扩展性上。然而，这些网络通常不具有用于分发文件的管理机制。因此，P2P文件共享网络中的版权侵权已经变得普遍。为了防止非法的文件分发，几家反P2P公司已经通过索引中毒来控制文件分发。虽然索引中毒的目的是通过在P2P网络中散布大量的虚拟元数据来混淆使用，但其影响尚未得到很好的研究。在本文中，我们将索引中毒的Winny网络，在日本最流行的P2P文件共享网络之一，控制文件分发。我们的评估包括由超过100，000个活跃对等点组成的实时Winny网络中的索引中毒。实验结果表明，与不加控制的情况相比，我们提出的方法可以将查询命中率降低到0.004%以下，并且索引中毒对控制少量文件是有效的。然而，结果也表明，索引中毒可能会造成严重损害的Winny网络，当许多文件是在我们的控制下，同时。
Peer-to-Peer (P2P) file sharing networks have witnessed dramatic increase in popularity for the past few years. In order to meet the demand of users, most P2P file sharing networks have been primarily focusing on improving transmission efficiency and network scalability. However, these networks do not usually have management mechanisms for distributing files in general. Consequently, copyright infringements in P2P file sharing networks have become prevalent. In order to prevent illegal file distribution, several anti-P2P companies have controlled the file distribution by index poisoning. Although index poisoning aims to obfuscate uses by diffusing a lot of dummy metadata in P2P networks, its effects have not been well studied yet. In this paper, we apply index poisoning to a Winny network, one of the most popular P2P file sharing networks in Japan, to control the file distribution. Our evaluation includes index poisoning in a live Winny network composed of over 100,000 active peers. The result shows that our proposed method can decrease the number of query hits to less than 0.004% compared to the case without our control, and that index poisoning is effective to control a small number of files. However, the result also shows that the index poisoning could cause a serious damage on a Winny network, when many files are under our control simultaneously.
