ICANN Convenes Design Team to Evolve Root Zone Security

21 February 2023

The Internet Corporation for Assigned Names and Numbers (ICANN) is pleased to announce the members of a newly formed Root Zone Algorithm Rollover Study Design Team, marking an important step in the advancement of this project.

The team's goal is to develop a plan for changing the cryptographic algorithm used for the Domain Name System (DNS) root key signing and zone signing keys. The team aims to help the ICANN community and ICANN's global partners be technically and operationally prepared for the future change in the signing algorithm. The change will enhance the security of the DNS.

Developing a plan to safely change the algorithm is a proactive step in maintaining the security and stability of the root zone of the DNS. ICANN's management of the root zone is part of ICANN's mission to make the Internet secure, resilient, and interoperable for its billions of users. More about the project is available on this page. To learn about the DNS and ICANN's work, visit this page.

The team will conduct its work over the coming months. The team's proposals will be published for community review later this year through an ICANN Public Comment proceeding, which will inform further revisions.

The newly formed design team is composed of ICANN and its Internet Assigned Numbers Authority (IANA) staff, key stakeholders, and seven volunteer experts. The design team members, including support staff, are:

  • Arends, Roy (ICANN)
  • Eland, Howard (DNS Infrastructure Group)
  • Foley, Aaron (IANA)
  • Hoffman, Paul (ICANN)
  • Johnson, Jennifer (IANA)
  • Larson, Matt (ICANN)
  • Lavu, Ramana (Verisign)
  • Lewis, Edward (ICANN)
  • Mitchell, James (IANA)
  • Müller, Moritz (Netherlands Domain Registration Foundation, SIDN)
  • Okubo, Tomofumi (DigiCert Inc.)
  • Pavez, Andres (IANA)
  • Rose, Scott (National Institute of Standards and Technology, NIST)
  • Schlyter, Jakob (Kirei)
  • Thomassen, Peter (deSEC/SSE Secure Systems Engineering)
  • Weber, Ralf (Akamai)
  • Wessels, Duane (Verisign)
  • Yoneya, Yoshiro (Japan Registry Services Co. Ltd.)

ICANN and IANA staff will continue to provide updates to the ICANN community about the design team's progress.


ICANN's mission is to help ensure a stable, secure, and unified global Internet. To reach another person on the Internet, you need to type an address – a name or a number – into your computer or other device. That address must be unique so computers know where to find each other. ICANN helps coordinate and support these unique identifiers across the world. ICANN was formed in 1998 as a nonprofit public benefit corporation with a community of participants from all over the world.
