The Internet was not designed with information controls, such as censorship or surveillance, in mind. However, its importance has led many nations to repurpose Internet protocols (e.g., the Domain Name System (DNS) and Border Gateway Protocol (BGP)), and network management products (e.g., Web proxies, traffic shapers) for information control. This unintended use of networking technologies can lead to unintended international impact of censorship, and raises many ethical issues when network management products are exported to countries that use them to violate human rights. To address these challenges, this project: (1) develops a platform which enables repeatable measurements of Internet censorship while mitigating risks to individuals performing the measurements, (2) designs techniques to analyze data from the platform to detect different types of censorship and even specific network management products used for censorship, and (3) uses the platform to quantify instances of national censorship which have unintended international impact on the Internet. The use of technology to restrict freedom of speech and persecute dissidents around the globe is a human rights concern. This project provides high fidelity technical data to inform policy discussions. Further, the technical analysis provides insights into the global impacts of national censorship on the Internet, and how proposed improvements to existing protocols (e.g., DNSSEC, BGPSEC) can mitigate these issues.

互联网不是考虑到审查或监视等信息控件的设计。但是，其重要性导致许多国家重新利用Internet协议（例如，域名系统（DNS）和Border Gateway协议（BGP）），以及网络管理产品（例如Web代理，流量塑造者）进行信息控制。这种意外的网络技术使用可能会导致审查制度的意外影响，并在将网络管理产品出口到使用它们侵犯人权的国家时提出了许多道德问题。 To address these challenges, this project: (1) develops a platform which enables repeatable measurements of Internet censorship while mitigating risks to individuals performing the measurements, (2) designs techniques to analyze data from the platform to detect different types of censorship and even specific network management products used for censorship, and (3) uses the platform to quantify instances of national censorship which have unintended international impact on the Internet.使用技术限制言论自由和迫害全球的持不同政见者是人权的关注。该项目提供了高保真技术数据，以告知政策讨论。此外，技术分析提供了对国家审查制度对互联网的全球影响的见解，以及对现有协议（例如DNSSEC，BGPSEC）的建议改进如何减轻这些问题。
