Key Signing Ceremonies
Ceremonies are usually conducted four times a year to perform operations using the Root Key Signing Key, and involving Trusted Community Representatives. In a typical ceremony, the KSK is used to sign a set of operational ZSKs that will be used for a three month period to sign the DNS root zone. Other operations that may occur during ceremonies include installing new cryptographic officers, replacing hardware, or generating or replacing a KSK.
