7.2.1. Secure Flash of DGX H100 Firmware
Secure Flash is implemented for the DGX H100 to prevent unsigned and unveried rmware images
from being ashed onto the system.
7.2.2. Encryption
Here is some information about encrypting the DGX H100 rmware.
The rmware encryption algorithm is AES-CBC.
▶ The rmware encryption key strength is 128 bits or higher.
▶ Each rmware class uses a unique encryption key.
▶ Firmware decryption is performed either by the same agent that performs signature check or a
more trusted agent in the same COT.
