If the signature is valid, the processor transitions into the Architectural Secure (AS) state, and execution jumps to the bootloader.

Implementing the trust architecture involves preparing the environment, signing images, and "fusing" the device. Step 1: Preparation and Key Generation Create your cryptographic key pairs ( RSAcap R cap S cap A ECDSAcap E cap C cap D cap S cap A

: Ensures only OEM-validated and digitally signed code can execute by verifying software integrity before launch.

Extract the SHA-256 hash of the Super Root Key public key table. This text string of hex values is what you will program into the SoC fuses. Phase 2: Compiling and Signing the Bootloader (U-Boot)
