Unfettered digital communication, as provided by the Internet, has fundamentally changed the world in countless ways. Businesses, organizations, and citizens have benefited from the Internet's global reach. However, the Internet was not designed to be resilient to censorship, and governments have restricted communication to advance their social and economic agendas. Worse, network equipment providers have shown a willingness to commoditize and profit from censorship by selling interception and filtering devices. The desire for uncensored access to the Internet has motivated the development of techniques such as one-hop proxies and anonymizing networks, but existing techniques have multiple limitations, ranging from low performance and intermittent availability to reduced levels of security and application flexibility. This project will develop and deploy a censorship resistant peer-to-peer system that overcomes the limitations of existing systems and provides unrestricted access to popular web sites and Internet services. The advent of social networks provides researchers with an opportunity to take a fresh look at peer-to-peer systems for censorship resistance. The focus of this project is to use social trust relations as a foundation for achieving highly secure and blocking resistant overlays for supporting network services, while also approaching the ease of use, performance, and reliability typically associated with direct communications. Specifically, the system will use social overlays wherein participants form a peer-to-peer overlay network bootstrapped based on real-world trust relationships. Participants of the social overlay would be able to directly communicate and share content, without having to expose their actions and without being blocked. A key design choice is also to develop the system to operate completely within a web browser, leveraging newly developed technologies that provide support for peer-to-peer communications inside the browser. Browser-based end-user solutions are easily deployable without requiring significant infrastructural costs. There are several key, interrelated challenges that the system will overcome. Principal among these are: performance, flexibility, trustworthiness, and robustness.

互联网提供的不受限制的数字通信从根本上以无数方式改变了世界。企业，组织和公民已经从互联网的全球范围中受益。 但是，互联网的目的不是旨在对审查制度有抵抗力，政府限制了沟通以推进其社会和经济议程。更糟糕的是，网络设备提供商表现出愿意通过销售拦截和过滤设备从审查制度中获利的意愿。 对未经审查的访问的愿望激发了单跳代理和匿名网络等技术的发展，但是现有技术具有多个限制，从低性能和间歇性可用性到降低的安全性和应用程序灵活性水平。 该项目将开发并部署抗审查的对等系统，该系统克服了现有系统的局限性，并提供了对流行网站和Internet服务的不受限制访问。 社交网络的出现为研究人员提供了一个机会，可以重新查看对等系统的审查制度。该项目的重点是利用社会信任关系作为实现高度安全和阻碍抗网络服务的高度安全和阻塞的基础，同时还可以接近通常与直接通信相关的易用性，性能和可靠性。 具体而言，该系统将使用社交叠加层，其中参与者基于现实世界的信任关系形成对等覆盖网络引导。 社会覆盖的参与者将能够直接交流和共享内容，而无需公开其行为而不会被阻止。 一个关键的设计选择也是开发系统以在网络浏览器中完全运行的系统，利用新开发的技术为浏览器内部的点对点通信提供支持。 基于浏览器的最终用户解决方案很容易部署，而无需大量基础设施成本。 系统将克服几个关键，相互关联的挑战。 其中的主要内容是：性能，灵活性，可信度和鲁棒性。
