Image Verification
During firmware updates, the image is verified by comparing a digital signature to
a computed signature on the image hash. During manufacturing, the hash value is
computed on the management firmware (MFW) and sent for a signature at the
Signature Authority (SA). The SA signs it using its private key, and then appends
the signature to the MFW.
When the MFW requires verification, the hash is calculated on the MFW. The
hash is compared with the signature after running the opposite algorithm using the
equivalent public-key.
Signature = Digital-Signature-Algorithm (Private-Key, HASH)
Verified if (HASH == Digital-Signature-Algorithm (Public-Key, Signature)
Upgrading Adapter Firmware on Linux
To upgrade the adapter firmware on a Linux system:
