Abstract
A Basic Input/Output System (BIOS) secure data management system includes a BIOS that is configured to perform a boot process. At least one memory system is configured to provide a System Management (SM) memory location that is only accessible by the BIOS. A trusted platform module (TPM) includes at least one register and is configured to store sealed first secure data. The TPM is configured to use at least one first value in the at least one register that depends on the boot process to unseal the sealed first secure data to provide unsealed first secure data, and provide that unsealed first secure data to the BIOS for storage in the SM memory location. The BIOS is configured to retrieve the unsealed first secure data from the SM memory location and use the unsealed first secure data to perform a security function.
