Monitoring and Controlling Content Access in KAD

We propose a new distributed architecture that aims to investigate and control the spread of contents in the KAD P2P network through the indexation of keywords and files. Our solution can control the DHT at a local level with a new strategy bypassing the Sybil attack protections inserted in KAD. For the targeted DHT entries, we can monitor all requests emitted by the peers, from the initial content publication or search, to the final download request of fake files, assessing accurately peers interest to access it. We demonstrate the efficiency of our approach through experiments performed on the worldwide KAD network.
