👍 7backspace09002024/03/19 A is answer! There are two kinds of keys in DNSSEC: a key-signing key (KSK) and a zone-signing key (ZSK). In Route 53 DNSSEC signing, each KSK is based on an asymmetric customer managed key in AWS KMS that you own. You are responsible for KSK management, which includes rotating it if needed. ZSK management is performed by Route 53.
