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one major problem with anonymous file-sharing networks is that the available content is highly reduced, mostly with outdated files, and non-anonymous networks, such as the BitTorrent network, are still the major source of content: we show that in a 30-days period, 21648 new torrents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.
