MultiProxy: a collaborative approach to censorship circumvention

Abstract

In recent years, many countries and administrative domains exploit control over their communication infrastructures to censor online materials. The concrete reasons behind the Internet censorship remain poorly understood due to the opaque nature of the systems. Generally, Internet censorship is to disrupt the free flow of information. It involves a series of steps to stop the dissemination of information, or prevent the access to information, for example, disrupt the link between the users and providers. These technologies bring significant inconvenience for legitimate users. The goal of the thesis is to undertake a recent study to measure the behaviour of the Great Firewall of China (GFW). Based on that, this work designs a Peer-to-Peer (P2P) circumvention system called MultiProxy which exploits the blockchain-based economical model in order to create a balanced environment for resources providing and consuming. The system also uses multi-hop messaging to protect the privacy of the request initiators. The evaluation results show that MultiProxy can evade censorship while protecting users privacy.
