ICANN housecleaning will revoke old DNS security key this week
The Internet Corporation for Assigned Names and Numbers will this week do some important housecleaning from its successful, first-ever cryptographic key change performed last October.
In October ICANN rolled out a new, more secure root zone Key Signing Key -2017 (KSK-2017) but the process wasn’t complete as the old key, KSK-2010 remained in the zone. On January 10 ICANN will revoke the old key and remove it from the root zone. The KSK helps protect the internet’s address book – the Domain Name System (DNS) and overall Internet security.
