The 2021 DNS Privacy workshop was again co-hosted by NDSS. This years conference was be a virtual online conference on Sunday, 21st February 2021.

 


2021 Topic: Measuring deployment and effectiveness of encrypted DNS.


Workshop topics 

This workshop will allow participants to contribute to the accelerating progress of DNS privacy technologies and deployment throughout the Internet. We aim to bring together a quorum to discuss these technologies, both established and emerging. Special focus will be on new measurements of encrypted DNS, and also the contributions that DNS privacy makes in civil society applications, in conjunction with related and newer technology. The program will be a mixture of accepted and invited talks, and open discussion.
