I.MX6 using HAB key in kernel

Hi all,

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.

Thank you.

Regards,

Tee

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,
