We have a AES key we are looking to store in a secure location. From the security manual it seems that SNVS has a OTP Master Key and a Zeroizable Master Key. We don't want to burn efuse to store a key as it would make it harder for us to update the key in the future so we don't want to go that route. For ZMK we don't have a battery cell to power SNVS_LP while our system is powered off so we would lose the key stored there. From reading on the DCP Key storage is it the same storage as the SNVS? Or is it a different key storage that we can utilize differently? From my understanding the DCP can use the SNVS keys so does that mean that the key storage for the DCP is the same as the SNVS key storage?
Thank you,
Alex
