Basic input/output system (BIOS)/unified extensible firmware interface (UEFI) hard drive authentication

Abstract:

A Basic Input/Output System (BIOS)/Unified Extensible Firmware Interface (UEFI) on a Self-Service Terminal (SST) processes during a boot of the SST. When a new hard disk is detected as being present and an identifier for the new hard disk is missing from a whitelist, a signed hard disk identifier is verified from storage on the new hard disk. If the signed hard disk identifier is verified: the new hard disk is authenticated, the whitelist is updated to include the new hard disk identifier, a unique identifier for BIOS/UEFI and the new hard disk identifier are written to the storage of the new hard disk, and the boot process is permitted to continue for the SST.
