This is a proof-of-concept for a technique, which involves
de-/encrypting the u-boot.img with a key derived from a hardware
fingerprint. This is
Hi Albert,
so if I get you right the workflow for payload authentication is the
following:
Encryption process:
1. Create hash value H for u-boot.img
2. Encrypt the hash value H with secret K to get encrypted hash values H_enc
3. Store H_enc
Decryption process:
1. Read H_enc
2. Decrypt H_enc us

Hi everyone,
I want to implement a minimal secure boot architecture into u-boot by
letting the u-boot.img be decrypted during SPL execution. Thus, the
u-boot.img is present on the MMC in an encrypted version. I already
implemented a basic AES-128 en-/decryption algorithm into the SPL.
