In recent years, peer-to-peer (P2P) networks have soared in popularity in the form of file sharing applications. With this popularity comes security implications and vulnerabilities. In this paper, we examining the framework on which most P2P networks are built, and from this, we examine how attacks on P2P networks leverage the very essence of the networks itself: decentralization of resources ...

Peer-to-peer applications (P2P) are no longer limited to home users, and start being accepted in academic and corporate environments. While file sharing and instant messaging applications are the most traditional examples, they are no longer the only ones benefiting from the potential advantages of P2P networks. For example, network file storage, data transmission, distributed computing, and co...

Structured peer-to-peer overlay networks have recently emerged as good candidate infrastructure for building novel large-scale and robust Internet applications in which participating peers share computing resources as equals. In the past three year, various structured peer-to-peer overlay networks have been proposed, and probably more are to come. We present a framework for understanding, analy...

Peer-to-peer (P2P) systems are widely used to exchange content over the Internet. Knowledge on paedophile activity in such networks remains limited while it has important social consequences. Moreover, though there are different P2P systems in use, previous academic works on this topic focused on one system at a time and their results are not directly comparable. We design a methodology for com...

After almost two decades of research on anonymous network communication the development has forked into two main directions, namely Mix cascades and peer-to-peer (P2P) networks. As these design options have implications on the achievable anonymity and performance, this paper aims to elaborate the advantages and disadvantages of either concept. After clarifying the scope of the discussion, we pr...
