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创始原则，互联网已成为传达可能引起争议或被压制的最有效和常见的手段之一。在线言论自由的威胁是，私人和州利益均已广泛地对互联网审查进行了广泛的做法。这些审查员使用各种社会和技术手段来限制信息的可用性或表达，扼杀民主过程。该项目的重点是开发覆盖网络，通过规避社会和技术审查制度措施来促进言论自由。 该项目将开发新的软件和协议，以实现满足三个不同安全目标的安全覆盖网络：关系隐私，会员隐藏和阻止阻力。 该项目的次要重点是了解这些安全目标及其之间的关系，并研究现有系统满足这些属性的程度。该项目将培训本科生和研究生以执行和应用各种学科的研究（包括密码学，网络，网络，算法和编码理论）。 该项目还通过引入隐藏的新成员资格概念作为安全问题来开发新的智力基础架构。 最后，预计该项目的结果将包括对促进互联网上表达自由的自由软件的广泛传播，反对强烈反对这种表达的政权。
