PRESERVING PROTECTED SECRETS ACROSS A SECURE BOOT UPDATE
Obtaining a sealed secret. The method includes decrypting one or more BLOBs at a computing system from among a plurality of different BLOBs. Each of the BLOBs in the plurality of BLOBs contains the secret. Each of the BLOBs in the plurality of BLOBs is sealed to a different condition from among a pl...

| description | Obtaining a sealed secret. The method includes decrypting one or more BLOBs at a computing system from among a plurality of different BLOBs. Each of the BLOBs in the plurality of BLOBs contains the secret. Each of the BLOBs in the plurality of BLOBs is sealed to a different condition from among a plurality of conditions. A given condition is a reflection of a system state where the system state is indicative of whether or not the system can be trusted to receive the secret. The method further includes evaluating one or more of the conditions to determine if at least one of the one or more conditions is met. The method further includes, if at least one of the one or more conditions is met, then providing the secret to an external entity. |
