Achieving Dynamic Communication Path for Anti-Tracking Network

Abstract

The increasingly rampant network monitoring and tracing bring the huge challenge on the protection of netizens' privacy. The anonymous networks mitigate the threat of network monitoring and tracing to a certain degree, but the static communication path has become the weakness. To address the problem, we propose a tracking-resistant communication mechanism with dynamic paths(TresMep). Different with the stepping stone chain like Tor, TresMep provides a chain of node groups which include at least one honest node. The message is transferred between groups. Each group uses asynchronous DC-net to hide the exit node which deliver the message to the honest node of the next group, and each group randomly chooses the exit node in each round of transmission through lagrange interpolation. Then, the transmission path would be changed dynamically and randomly to provide stronger tracking-resistance. The experimental results show that TresMep has a stronger performance of trackingresistance than the stepping stones based anti-tracking network with static communication path. The communication efficiency of TresMep is also satisfactory. But when message load is big, the communication efficiency of TresMep becomes worse. TresMep takes a tradeoff between tracking- resistance and communication efficiency.
