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.

互联网的自由和开放正受到威胁。非民主国家的政府审查人员正在部署网络过滤器，以阻止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他们的人权，如言论自由和集会自由。该项目旨在为今天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，抵制审查必须不再是一个临时的、附加的组成部分，而是成为网络基础设施的一流属性。与现有的容易识别和阻止的规避工具相比，审查由该项目开发的通信技术会给潜在的审查者带来巨大的技术、经济和社会成本。该项目包括几个研究推动力。第一个推动力是将对抗审查通信的支持直接整合到流行的网络服务(例如云存储和流媒体视频)中，这些服务已经提供加密频道，在不造成重大中断的情况下很难被屏蔽。第二个重点是新的多流传输协议和无处不在的代理系统，它们在设计上隐藏了传输的信息的内容，从而抵抗了审查。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的机制。总而言之，该项目旨在生产抗审查的通信系统和网络协议，帮助数百万潜在用户访问免费互联网，在世界各地鼓励和促进民主和人权。
