Using randomized routing to counter routing table insertion attack on Freenet

摘要

As privacy becomes an increasingly important issue on today's Internet, attacks on anonymous tools gain more attention. In this paper, we investigated countermeasures to a routing table insertion (RTI) attack on Freenet. We analyzed the key factors supporting the RTI attack, and proposed a simple randomized routing method to mitigate the RTI or similar attacks. We implemented the proposed method on the Freenet Thynix simulator. Our results show that the proposed method works well on small world topologies and thus a feasible choice to deal with the RTI attack on Freenet. We are further investigating more effective countermeasures based on these results.
