Authenticating the internet from end-to-end.
Developing DNSSEC since the Beginning
Verisign has been involved in DNSSEC development since 2000 and our engineers played a leading role in the development of the DNSSEC Hashed Authenticated Denial of Existence (NSEC3) protocol. As DNSSEC testing, implementation and adoption move forward, we continue to collaborate with the internet technical community and participate in industry organisations.
Domain Name System Security Extension (DNSSEC) can strengthen trust in the internet by helping to protect users from redirection to fraudulent websites and unintended addresses.
In July 2010, Verisign—working with the Internet Assigned Numbers Authority (IANA) and the U.S. Department of Commerce (DoC)—completed deployment of DNSSEC in the root zone (the starting point of the DNS hierarchy). Verisign also enabled DNSSEC on .edu in July in collaboration with EDUCAUSE and the DoC, on .net in December 2010 and on .com in March 2011. DNSSEC adoption has progressed since 2011, with a little more than 1/3 of the registries which operate top-level domains (TLDs) now being signed.
In addition, we are taking many steps to help members of the internet ecosystem take advantage of DNSSEC. These steps include publishing technical resources, providing an Operational Test Environment, leading educational sessions, participating in industry forums and developing tools to simplify DNSSEC management.
Verisign is committed to serving as a trusted steward of the internet. As the registry for .com and .net and a provider of critical internet infrastructure services, our goal is to enable the internet’s future innovations while protecting the internet community from new and emerging cyber attacks. Our work on DNSSEC is another step in our ongoing fortification of and investment in, critical internet infrastructure.
