Executive Summary

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, the authors present a study that motivates the integration of both worlds. They provide a performance comparison of both DHTs in terms of publishing efficiency. They investigate the security threats and show that the current BitTorrent Mainline DHT is much more vulnerable to attacks than KAD.
