Introducing OGR — a new approach to anonymous IP datagram transmission based on the Chaumian ‘onion’ encryption and the KISS principle

Abstract The goal of this paper is to introduce a technique, called ‘OGR’, that allows anonymous transmission of IP datagrams of any kind. During the last decade numerous anonymizing solutions implementing the Chaumian ‘onion’ encryption have been proposed. Many of them are dedicated to specific services: either anonymous mail delivery or anonymous storage sharing, while the other ones, referred as low-latency systems, work real-time and are able to anonymize any TCP streams (with preference to http), but poorly deal with or even don’t support other transports. ‘OGR’ is strongly inspired by the original Chaumian Mix-net model and aims at universality (the ability to work at the level of IP datagrams rather than upper-layers protocols) and maximal simplicity (the KISS principle). It discards the idea of fixed circuits (or cascades) present in most low-latency solutions in favor of independent, intelligent packets. Although this approach may occur less efficient for huge data streams it’s able to handle any request-reply protocols including those operating over UDP as well as all applications where other transports or raw IP packets are to be used.
