Anonymous communications are growing extremely fast because more and more Internet users employ anony mous systems, such as the I2P or Tor networks, as a way to hide their online activity. Therefore, these networks have been more and more studied, mainly from a security point of view. Different studies have shown important design flaws in these systems that could break users' anonymity and how these...
The I2P network provides an abstraction layer allowing two parties to communicate in an anonymous manner. This network is optimised for anonymous web hosting and anonymous file-sharing. I2P's file- sharing community is highly active where users deploy their file-sharing applications on top of the network. I2P uses a variation of Onion routing, thus assuring the unlinkability between a user and its...
Anonymous communications have been exponentially growing [1], [2], where more and more users are shifting to a privacy-preserving Internet and anonymising their peer-to-peer communications [3]. Anonymous systems allow users to access different services while preserving their anonymity. We aim to characterise these anonymous systems, with a special focus in the I2P network [4].
The current wave of evolution that leads BitTorrent towards a fully decentralized architecture is both promising and risky. Related work demonstrates that BitTorrent's Mainline DHT is exposed to several identified security issues. In parallel, the KAD DHT has been the core of intense research and was improved over years. In this paper, we present a study that motivates the integration of both worlds...
