Wooding was one of seven people in the world entrusted by the Internet Corporation for Assigned Names & Numbers (ICANN) with a special cryptographic ‘smart-card’ that holds part of a key used to generate the Domain Name Server Security Extensions (DNSSEC) protocol that protects Internet domain names.
In addition, they support the TSIG protocol, which allows DNS clients to establish a secure session with the server to publish Dynamic DNS records or to request secure DNS lookups without incurring the cost and complexity of full DNSSEC support.
