The University of Chicago received a three-year, $500,000 Project Grant award from the National Science Foundation to study practical deployment considerations for decentralized, encrypted Domain Name System (DNS) protocols. The NSF Division of Computer and Network Systems awarded the grant under the Computer and Information Science and Engineering program, which supports investigator-initiated research and education in computing, communications, and information science and engineering.
The University will research the performance and privacy properties of existing encrypted DNS protocols like DNS over HTTPS and DNS over TLS to understand their practical deployment. It will evaluate these protocols' effects on DNS lookup time and application performance metrics like web page load time. It will also explore prospects for re-decentralizing the DNS through distributing clients' DNS queries across multiple recursive resolvers. Finally, the project will develop a coherent architectural framework integrating various DNS privacy approaches from encryption to previous work on Oblivious DNS. Results will contribute to knowledge on DNS performance and privacy and be released to the community.
