TCR or Trusted Community Representative is a term given by ICANN to those who hold the keys to DNSSEC of Internet. Every TCR has been given a part of the master key. The first key signing ceremony took place on 16th June 2010. ICANN has taken this decision to avoid any terrorist attack or any other catastrophic event on the Internet. If it ever happened, the TCRs will meet at one place, generate a master key and will reboot the DNS. They are not rebooting the entire Internet, as many news outlets have stated, but rather rebooting the DNSSEC protocols, implemented in 2010, that protect the DNS.[1] There are twenty-one TCRs selected by ICANN around the globe.[2][3]

Every TCR is given two identical copies of a smartcard, sealed in a tamper-evident bag, that contain encrypted parts of the root DNSSEC key.
