NXP_DIE_DICE_UDS_MK_SK in ELS key slots on MCXN947

[YosukeW]

Hello,

I want to use NXP_DIE_DICE_UDS_MK_SK as input key of HKDF to derive the secret on MCXN947.
But, secure reference manual doesn't describe precise slot number of it.
I found some other keys like NXP_DIE_MK_SK in 9.9 ELS key store state after boot.

Could you please tell me it ?

Thank you and Best regards, Yosuke

Hello @YosukeW 

Yes, the MCXN947 Security Reference Manual does not cover this topic. I will confirm with our internal team and update you as soon as I have any new information.

Thank you.
