PHI: Path-Hidden Lightweight Anonymity Protocol at Network Layer
2017
Proceedings on Privacy Enhancing Technologies
We identify two vulnerabilities for existing highspeed network-layer anonymity protocols, such as LAP and Dovetail. First, the header formats of LAP and Dovetail leak path information, reducing the anonymity-set size when an adversary launches topological attacks. Second, ASes can launch session hijacking attacks to deanonymize destinations. HORNET addresses these problems but incurs additional bandwidth overhead and latency. In this paper, we propose PHI, a Path-HIdden lightweight anonymity
