Freedom of speech is a founding principle of democratic society, and the Internet has become one of the most effective and common means of conveying expression that is likely to be controversial or suppressed. One threat to the freedom of speech online is the now widespread practice of Internet censorship by both private and state interests. These censors use a variety of social and technological means to limit availability or expression of information, stifling the democratic process.This project is focused on developing overlay networks that promote freedom of speech by circumventing social and technological censorship measures. The project will develop new software and protocols for secure overlay networks that satisfy three distinct security goals: relationship privacy, membership hiding, and blocking resistance. A secondary focus of the project is on understanding these security goals and the relationships between them, and investigating the extent to which existing systems satisfy these properties.The project will train undergraduate and graduate students to perform and apply research from a variety of disciplines (including cryptography, networking, algorithms, and coding theory). The project also develops new intellectual infrastructure by introducing the new notion of membership hiding as a security problem. Finally, the results of the project are expected to include the broad dissemination of free software that promotes freedom of expression on the Internet, against regimes that strongly oppose such expression.

言论自由是民主社会的一项基本原则，互联网已成为最有效和最常见的表达可能受到争议或压制的言论的手段之一。对网上言论自由的一个威胁是现在普遍存在的私人和国家利益集团的互联网审查做法。这些审查员使用各种社会和技术手段限制信息的提供或表达，扼杀民主进程，本项目的重点是开发覆盖网络，通过规避社会和技术审查措施促进言论自由。 该项目将为安全覆盖网络开发新的软件和协议，以满足三个不同的安全目标：关系隐私，成员身份隐藏和抗阻塞。 该项目的第二个重点是了解这些安全目标和它们之间的关系，并调查现有系统满足这些属性的程度。该项目将培养本科生和研究生执行和应用各种学科（包括密码学，网络，算法和编码理论）的研究。 该项目还通过引入成员隐藏作为安全问题的新概念来开发新的智能基础设施。 最后，预计该项目的成果将包括广泛传播促进互联网上表达自由的自由软件，反对强烈反对这种表达的政权。
