Call for Volunteers as Trusted Community Representatives

The Internet Corporation for Assigned Names and Numbers (ICANN) is seeking interested individuals who wish to act as Trusted Community Representatives (TCRs). These individuals play an important role in managing the Root Zone Key Signing Key (KSK), the trust anchor for the global Domain Name System (DNS). By inviting recognized members of the DNS technical community to be part of the Root Zone KSK operations, the ICANN organization seeks to improve transparency and confidence in the Domain Name System Security Extensions (DNSSEC) security mechanism among the wider Internet community.

About the TCR Role

TCRs serve as one of the multi-layered safeguards that protect the key material used to secure the DNS Root Zone.

There are two primary types of TCRs: cryptographic officers, who are actively involved in Root Zone KSK ceremonies conducted throughout the year; and recovery key share holders, who are involved in our disaster recovery planning. The cryptographic officers make a commitment to travel to a least one Root Zone KSK ceremony per year.

All TCRs maintain custody of essential pieces required for the successful operation of the Root Zone KSK. To guard against unauthorized access, management of the KSK is spread across multiple individuals who must come together to operate the key.

TCRs are ambassadors on behalf of the broader technical and operational communities. To support trust in the system, TCRs report back to the community that the Root Zone KSK is being managed in an appropriate and trustworthy way.

All TCRs need to maintain a state of readiness should there be an unforeseen need to hold a ceremony at short notice.

Travel support is provided to TCRs who need to attend ceremonies. This support includes arranging and paying for airfare and accommodation, and providing a stipend for incidental costs.

More Information

Those who are interested in applying to be a TCR are invited to review detailed materials posted on the IANA website, which includes the process to submit a statement of interest. Statements of interest will be collected and assessed to fill current vacancies, and in the event of new vacancies. Visit here for these materials.

About ICANN

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 into your computer or other device – a name or a number. 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 not-for-profit public-benefit corporation and a community with participants from all over the world. For more information, please visit: https://www.icann.org.

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as""icann.org"" is not an IDN."
