Abstract | Supporting decentralized peer-to-peer communication between users is crucial for maintaining privacy and control over personal data. State-of-the-art protocols mostly rely on distributed hash tables (DHTs) in order to enable user-to-user communication. They are thus unable to provide transport address privacy and guaranteed low path stretch while ensuring sub-linear routing state together with tolerance of insider adversaries. In this paper we present U-Sphere, a novel location-independent routing protocol that is tolerant to Sybil adversaries and achieves low O (1) path stretch while maintaining View the MathML source per-node state. Departing from DHT designs, we use a landmark-based construction with node color groupings to aid flat name resolution while maintaining the stretch and state bounds. We completely remove the need for landmark-based location directories and build a name-record dissemination overlay that is able to better tolerate adversarial attacks under the assumption of social trust links established between nodes. We use large-scale emulation on both synthetic and actual network topologies to show that the protocol successfully achieves the scalability goals in addition to mitigating the impact of adversarial attacks. |
