Node lookup mechanisms constitute an integral part of any overlay network, and hence also of anonymous communication networks. Today, most anonymizers use centralized directories, ...
The ability to locate random relays is a key challenge for peer-to-peer (P2P) anonymous communication systems. Earlier attempts like Salsa and AP3 used distributed hash table look...
We analyze information leaks in the lookup mechanisms of structured peer-to-peer anonymous communication systems and how these leaks can be used to compromise anonymity. We show t...
We introduce Torsk, a structured peer-to-peer low-latency anonymity protocol. Torsk is designed as an interoperable replacement for the relay selection and directory service of th...

There are many structured P2P systems that use DHT technologies to map data items onto the nodes in various ways for scalable routing and location. Most of the systems require O(lo...
