SGX BIOS for preboot

Jump to solution

Hi,

If we build a special algorithm in the BIOS for preboot., Can I add SGX in that?  If yes, what step and tool chain to do it?

-Thanks

Hi Sam,

We are not supporting SGX in Pre-Boot Environment(UEFI/BIOS). SGX is and was designed to be an Application TEE (which implies an OS is resident). We haven't seen usage models in the pre-boot environment that have justified the effort to resolve some of the difficulties in enabling in Pre-boot, allowing residence from boot, or resetting the TCB recovery infrastructure (which is predominantly hidden from most users) when transitioning between UEFI and OS.

Thanks and Regards,
