TWC: Medium: Collaborative: Hiding Hay in a Haystack: Integrating Censorship Resistance into the Mainstream Internet

互联网的自由和开放受到威胁。 非民主国家的政府审查机构正在部署网络过滤器，以封锁未经审查的信息来源，压制异议，并阻止公民使用互联网行使言论自由和集会自由等人权。该项目旨在为当今和未来的互联网提供强大的抗审查通信系统。 这项研究背后的主要原则是，审查阻力必须不再是一个特设的，附加组件，而是成为网络基础设施的一流属性。 现有的规避工具很容易识别和屏蔽，与此相反，审查该项目开发的通信技术对潜在的审查者来说需要付出巨大的技术、经济和社会代价。该项目包括几个研究方向。 第一个重点是将对审查抵抗通信的支持直接集成到流行的网络服务（例如，云存储和流媒体视频）中，这些服务已经提供加密通道，并且在不造成重大中断的情况下无法轻易阻止。 第二个重点是致力于新的多流传输协议和无处不在的加密系统，通过设计，隐藏传输信息的内容，从而抵抗审查。 第三个重点是研究未来互联网架构中的审查风险，以及为这些架构设计和实施抵制审查机制，总之，该项目旨在开发抵制审查的通信系统和网络协议，帮助数百万潜在用户免费使用互联网，鼓励和促进全世界的民主和人权。

Freedom and openness of the Internet are under threat. Government censors in non-democratic countries are deploying network filters to block sources of uncensored information, suppress dissent, and prevent citizens from using the Internet to exercise their human rights such as freedom of speech and freedom of assembly.This project aims to deliver robust censorship-resistant communication systems for today's and future Internet. The main principle behind this research is that censorship resistance must cease being an ad-hoc, add-on component and instead become a first-class property of the networking infrastructure. In contrast to the existing circumvention tools, which are easy to recognize and block, censoring the communication technologies developed by this project comes at a significant technical, economic, and social cost to the would-be censors.The project encompasses several research thrusts. The first thrust is integrating support for censorship-resistant communications directly into popular networked services (for example, cloud storage and streaming video) that already provide encrypted channels and cannot be easily blocked without causing significant disruption. The second thrust is devoted to new multi-streaming transport protocols and ubiquitous proxying systems that, by design, hide the contents of transmitted information and thus resist censorship. The third thrust is the study of censorship risks in future Internet architectures, as well as the design and implementation of censorship resistance mechanisms for these architectures.In summary, this project aims to produce censorship-resistant communication systems and networking protocols that help make free Internet accessible to millions of potential users, encouraging and fostering democracy and human rights throughout the world.
