Dr. Rick Lamb, ICANN's Senior Program Manager of DNSSEC, recently toured several European countries, as part of ongoing work from ICANN's Security, Stability and Resiliency (SSR) Team, offering free workshops on DNS Security and DNSSEC to the Internet community.

Beginning in Tallinn, Estonia, Rick worked with the ccTLD registry for .ee (Estonia), which gathered key Internet stakeholders for a two-day in-depth DNSSEC training. The .lv (Latvia) registry organized a similar DNSSEC training in Riga, Latvia.

The support of these national registries makes it possible for ICANN to reach key stakeholders in local Internet ecosystems. The help and support is important for ICANN. Thank you, Eesti Interneti Sihtasutus and Nic.LV for your help organizing these workshops.

After the training in Latvia, Rick flew to Warsaw, Poland where he gave a keynote speech at the Security Case Study, a conference organized by the Polish Cybersecurity Foundation. Rick's speech, "Cybersecurity, Keys and Hollywood: The truth about the Internet's phonebook and the 7 Keyholders," included hands-on audience involvement and was very well received, with a robust question and answer session.

After the conference, Rick conducted an information session for government representatives, ISPs and energy providers, organized by the Polish registry NASK, where he explained how these institutions could benefit from DNSSEC workshops. Thank you to NASK for helping ICANN gather important stakeholders.

He also gave a talk at Hackerspace Warsaw, which was well received and ran almost twice the expected time due to the amount of questions.

Rick then attended ION Malta, a conference organized by the Internet Society in Malta. He gave two presentations, an introduction to DNSSEC and an explanation of DNS-Based Authentication of Named Entities (DANE) and the future of Transport Layer Security (TLS). The following day, Rick gave a one-day DNSSEC training workshop attended by participants from the .mt (Maltese ccTLD registry), the Malta Information Technology Agency and others.

    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"""" is not an IDN."
