Abstract
We present , a system designed to provide anonymity and unobservability for real-time instant messaging and voice-over-IP communications against a global passive adversary. The system uses a relay based anonymization mechanism where circuits are routed over a social network in a peer-to-peer fashion, using full padding strategies and separate epochs to hide connection and disconnection events. Unlike established systems, gives away the identity of a user's friends to guarantee the unobservability of actual calls, while still providing anonymity when talking to untrusted third parties. We present the core design and components of , we discuss the key ways in which it challenges our current concepts of anonymity and provide an initial simulation-based security analysis. © 2010 Springer-Verlag Berlin Heidelberg.
