Abstract
Systems and methods for security for a split-boot architecture are described. In an illustrative, non-limiting embodiment, an Information Handling System (IHS) may include: a printed circuit board; a processor coupled to the printed circuit board; and a memory coupled to the processor, wherein the memory comprises program instructions stored thereon that, upon execution by the processor, cause the IHS to: obtain one or more cryptographic keys associated with firmware onboard the printed circuit board; and verify extended firmware using the cryptographic keys.
Claims20
An Information Handling System (IHS), comprising:
- a printed circuit board;
- a processor coupled to the printed circuit board;
- and
- a memory coupled to the processor, wherein the memory comprises program instructions stored thereon that, upon execution by the processor, cause the IHS to:
- obtain one or more cryptographic keys associated with firmware onboard the printed circuit board;
- and
- verify extended firmware using the cryptographic keys.
A method, comprising:
- obtaining one or more cryptographic keys associated with firmware onboard a printed circuit board;
- and
- verifying, in a split boot architecture, extended firmware using the cryptographic keys.
One or more non-transitory computer-readable storage media storing program instructions, that when executed on or across one or more processors of a circuit board in an Information Handling System (IHS), cause the IHS to:
- obtain one or more cryptographic keys associated with firmware onboard the circuit board;
- and
- verify, in a split boot architecture, extended firmware using the cryptographic keys.
