The Domain Name System: A Cryptographer’s Perspective

This is the first in a multi-part blog series on cryptography and the Domain Name System (DNS).

As one of the earliest protocols in the internet, the DNS emerged in an era in which today’s global network was still an experiment. Security was not a primary consideration then, and the design of the DNS, like other parts of the internet of the day, did not have cryptography built in.

Meeting the Evolving Challenges of COVID-19

The COVID-19 pandemic, when it struck earlier this year, ushered in an immediate period of adjustment for all of us. And just as the challenges posed by COVID-19 in 2020 have been truly unprecedented, Verisign’s mission – enabling the world to connect online with reliability and confidence, anytime, anywhere – has never been more relevant. We are grateful for the continued dedication of our workforce, which enables us to provide the building blocks people need for remote working and learning, and simply for keeping in contact with each other.

A Balanced DNS Information Protection Strategy: Minimize at Root and TLD, Encrypt When Needed Elsewhere

Over the past several years, questions about how to protect information exchanged in the Domain Name System (DNS) have come to the forefront.

One of these questions was posed first to DNS resolver operators in the middle of the last decade, and is now being brought to authoritative name server operators: “to encrypt or not to encrypt?” It’s a question that Verisign has been considering for some time as part of our commitment to security, stability and resiliency of our DNS operations and the surrounding DNS ecosystem.

Verisign Q3 2020 Domain Name Industry Brief: Internet Grows to 370.7 Million Domain Name Registrations

Today, we released the latest issue of the Domain Name Industry Brief, which shows that the third quarter of 2020 closed with 370.7 million domain name registrations across all top-level domains (TLDs), an increase of 0.6 million domain name registrations, or 0.2 percent, compared to the second quarter of 2020.1,2 Domain name registrations have grown by 10.8 million, or 3.0 percent, year over year.1,2

Maximizing Qname Minimization: A New Chapter in DNS Protocol Evolution

Data privacy and security experts tell us that applying the “need to know” principle enhances privacy and security, because it reduces the amount of information potentially disclosed to a service provider — or to other parties — to the minimum the service provider requires to perform a service.  This principle is at the heart of qname minimization, a technique described in RFC 7816 that has now achieved significant adoption in the DNS.

Chromium’s Impact on Root DNS Traffic

This article originally appeared Aug. 21, 2020 on the APNIC blog.

Introduction

Chromium is an open-source software project that forms the foundation for Google’s Chrome web browser, as well as a number of other browser products, including Microsoft Edge, Opera, Amazon Silk, and Brave. Since Chrome’s introduction in 2008, Chromium-based browsers have steadily risen in popularity and today comprise approximately 70% of the market share.1
