Garbled Routing (GR): Towards Unification of Anonymous Networks

Anonymous communication systems conceal the identity of the communicating parties to preserve their privacy. Various approaches exist, yet none is taking advantage of the diversity of available solutions to offer a higher anonymity. This paper introduces a generic framework, a higher level host network architecture, that allows mixture of various communication protocols. Our proposal can be gradually adopted by the existing networks. Obtained results include a potentially higher anonymity for all guest networks, and a pathway towards sharing user-bases, mixing the low-and high-latency communication, and benefiting from security-by-obscurity. As a result of mixing various protocols, some level of network unobservability will be achieved. This paper presents the design of our framework, modelling of guest networks, and results of our experiments.
