  • System and method for providing a secure locally-based boot disk encryption key
    Patent number: 12058256
    Abstract: A system and method for operating a terminal such as an automated teller machine or other type of self-service terminal having a primary partition of a hard disk encrypted with a disk encryption key (DEK). At the initial installation and after every boot, a pre-boot manager encrypts the DEK with a new key encryption key (KEK) and then splits the encrypted DEK into a plurality of encrypted DEK parts. The pre-boot manager next stores the plurality of encrypted DEK parts in randomized storage locations on an unallocated portion of a hard disk and encrypts a list of the randomized storage locations of the plurality of encrypted DEK parts with the KEK and storing the encrypted list in a location on the unallocated portion of the hard disk. Finally, the pre-boot manager stores the KEK, optionally in an obfuscated format, in a location on the unallocated portion of the hard disk.
