Secure Boot Key management for notebooks

Figure 6. HP Platform Key Management for notebooks.

Factory-default HP BIOS will have the HP platform key (PK), Microsoft key exchange key (KEK), Microsoft database (db), an empty blacklist database (dbx) populated, and the system will be in User Mode. No new PK enrollment is allowed. The HP Platform Key is different from the HP firmware-signing key. For the first implementation (starting with 2012), the HP PK is a certificate named “Hewlett-Packard UEFI Secure Boot Platform Key” issued by HP. The BIOS signing key is RAW-CMIT- BIOS2012. The Microsoft KEK is a certificate named “Microsoft Corporation KEK CA 2011.”

The User Mode section will be grayed out. The information will be listed but not changeable. The Clear Secure Boot Keys selection will also be grayed out. After the user disables Secure Boot, the Clear Secure Boot Keys option will be available.

Simply disabling Secure Boot will not change the mode. While still in User Mode, the keys currently enrolled in the system are preserved and the remainder of the section is grayed out. The user then has to then select Clear Secure Boot Keys. Then the BIOS goes to “Setup User Mode” (Figure 7) and the mode section becomes available.

Now that the system is in Setup Mode, the user can choose HP Factory keys versus Customer Keys. When the user selects Customer Keys, there is actually no key in the BIOS database. The user has to use an application in the OS to get the keys (PK, KEK, dbx) into the BIOS.

Note

If the user tries to import the HP PK again when the selection is the Customer Keys, the BIOS will reject the PK.
