Hello Team,
1. What are critical security parameters provided by IMX93 Hardware?
e.g. HUK, ROT Public Key, Attestation eKey
2. Can we update those critical security parameters by OTA?
@Harvey021 Can you please provide any Document which can explain this in Depth?
From SRM, ELE API (i.MX 93 Applications Processors Family | NXP Semiconductors), you can find some information helpful.
Regards
Harvey
@Harvey021 I have gone through Doc but i could not find anything about attestation key
That contains values used by ELE which defines the behvaiour of the chip, secure debug etc in addition to the attestation key and hardware unique key, OTFAD key, OEM keys etc. It should be difficult to update using OTA.
