Is there any example where i can use the private key that was fused inside the i.mx6 chip (for secure boot) to do some authentication of some files during kernel boot up?
I had managed to fused the key into i.mx6 chip, and managed to authenticate u-boot (from boot ROM) and kernel (from u-boot). However, i have no idea how to continue to use the key in kernel to further authenticate some files in filesystem.
Any help is appreciated.
I send the document and application note to you for reference,
if you don't think this is enough, do you mind creating a ticket, then I sent the mail to you. because this is security part, I'm not sure I can share these information publicly,
