Hi, NXP support team
We can use kernel-level Keystor API with CAAM, which can transform a plain key_file to a safe blob_file. As you kown i.mx6ull do not have CAAM.
So how to store keys safely and unique in each i.mx6ull chip?
You can refer to this document https://www.nxp.com/docs/en/application-note/AN4581.pdf
hi, Rita Wang
this doc i have read through without find a solution. i find another doc named
to encrypt keys. it is "CAAM Secure Memory Key Blob Generation", CAAM is needed.
As you know i.mx6ull do not have CAAM, so How can i implement a similar function in i.mx6ull？
The NXP Linux BSP supports only CAAM based hardware acceleration via CryptoDev interface.
i.MX 6ULL does not have CAAM.
you means i.mx6ull do not support uniquely keys crypto?
