Censorship-Resistant Communication over Public Networks
نویسنده
چکیده
The rapid growth of peer-to-peer networks and social networking websites has demonstrated the internet’s potential as a medium for grassroots collaboration. This report describes ongoing research into the use of friend-to-friend overlay networks for censorship-resistant communication. Decentralised mechanisms for resource allocation, unforgeable acknowledgements and adaptive routing are proposed.

Private and censorship-resistant communication over public networks
Society’s increasing reliance on digital communication networks is creating unprecedented opportunities for wholesale surveillance and censorship. This thesis investigates the use of public networks such as the Internet to build robust, private communication systems that can resist monitoring and attacks by powerful adversaries such as national governments. We sketch the design of a censorship-...
متن کاملNon-Hierarchical Networks for Censorship-Resistant Personal Communication
The Internet promises widespread access to the world’s collective information and fast communication among people, but common government censorship and spying undermines this potential. This censorship is facilitated by the Internet’s hierarchical structure. Most traffic flows through routers owned by a small number of ISPs, who can be secretly coerced into aiding such efforts. Traditional cryp...
متن کاملAn Adaptive Routing Protocol for Censorship-Resistant Communication
In open-membership networks such as peer-to-peer overlays and mobile ad hoc networks, messages must be routed across an unknown and changing topology where it may not be possible to establish the identities or trustworthiness of all the nodes involved in routing. This paper describes a decentralised, adaptive routing protocol in which nodes use feedback in the form of unforgeable acknowledgemen...
متن کاملEnhancing Censorship Resistance in the Tor Anonymity Network
The Tor network was originally designed as low-latency anonymity network. However, over time Tor earned a reputation as also being a useful tool to circumvent Internet censorship—at times, the network counted 30,000 users only from China. Censors reacted by tightening their grip on the national communication infrastructure. In particular, they developed different techniques to prevent people fr...
متن کاملIP over Voice-over-IP for censorship circumvention
Open communication over the Internet poses a serious threat to countries with repressive regimes, leading them to develop and deploy networkbased censorship mechanisms within their networks. Existing censorship circumvention systems face different difficulties in providing unobservable communication with their clients; this limits their availability and poses threats to their users. To provide ...
