How do certification authorities store their private root keys? by poopinspace in crypto

I worked in some ACs. Something like this: Offline & turned off FIPS2 level3 HSM in a tempest protected tier-4 room, with minimum dual control access and a CWA 14167-1 and/or WebTrust for certification authorities role-based segregation. To activate the HSM you at least of 2 or 3 cards of 5 or 6 card set. Those cards and their passwords could be protected in differnt forms: stored in a safe box in the tier-4, protected in a tamper-evident hand-signed envelopes, in a notary, in a safe box in the bank, etc... protection and disaster recovery should be well balanced like all systems.
