随着隐私和匿名问题的出现，匿名通信越来越受到互联网用户的关注。专用的匿名网络，如Freenet和I2P，允许用户之间匿名共享文件。然而，匿名文件共享网络的一个主要问题是可用的内容大大减少，大部分是过时的文件，而非匿名网络，如BitTorrent网络，仍然是内容的主要来源：我们显示，在30天的时间里，BitTorrent社区引入了21648个新的种子，而匿名I2P网络只引入了236个，用于四种不同类别的内容。因此，这些匿名网络的用户如何在不损害其匿名性的情况下访问这些不同的非匿名内容？在本文中，我们提出了第一个互联网模型，允许匿名用户在保持匿名的情况下访问和共享大型公共社区中的内容，从而提高了匿名环境中的内容可用性。我们表明，我们的方法可以有效地互连I2P用户和公共bt群，而不会影响他们的匿名性和他们的性能。我们的模型是完全实现的，并且可以自由使用。
Anonymous communication has gained more and more interest from Internet users as privacy and anonymity problems have emerged. Dedicated anonymous networks such as Freenet and I2P allow anonymous file-sharing among users. However, one major problem with anonymous file-sharing networks is that the available content is highly reduced, mostly with outdated files, and non-anonymous networks, such as the BitTorrent network, are still the major source of content: we show that in a 30-days period, 21648 new torrents were introduced in the BitTorrent community, whilst only 236 were introduced in the anonymous I2P network, for four different categories of content.Therefore, how can a user of these anonymous networks access this varied and non-anonymous content without compromising its anonymity? In this paper, we improve content availability in an anonymous environment by proposing the first internetwork model allowing anonymous users to access and share content in large public communities while remaining anonymous. We show that our approach can efficiently interconnect I2P users and public BitTorrent swarms without affecting their anonymity nor their performance. Our model is fully implemented and freely usable.
