Trusted Community Representatives
We seek to improve confidence and acceptance in the DNSSEC security mechanism among the wider Internet community by inviting recognized members of the DNS technical community to be part of the key generation, key backup and key signing process for the root.
As part of the joint effort to secure the domain name system (DNS) and the Root DNSSEC key management process, a number of persons acting as trusted representatives of the Internet community participate in the root key generation and signing ceremonies. These persons are called Trusted Community Representatives (TCRs).
Selection of TCRs is based on statements of interest, solicited from the Internet community. Persons considered directly affiliated with PTI, ICANN or VeriSign may not become a Trusted Community Representatives. Other interested parties may submit a statement of interest which will be considered when vacancies become available.
