As one of the most popular low-latency anonymous communication systems, Tor has been a great success but still faces some challenges, e.g., subject to low-resource attacks and no explicit mechanisms to explore tradeoffs between anonymity and performance. In this paper, the authors propose a Relay Recommendation System (RRS) for Tor to provide reliable relay information for building paths with better performance, mitigate low-resource attacks, and enable users to explore the tradeoffs between performance and anonymity based on their needs. They first present the design of RRS, and show its performance improvement and resistance to low-resource, high-resource, and reputation attacks.
