Qoriq - Trust Architecture 2.1 User Guide

The SEC block handles high-speed cryptographic operations, including RSA signature verification and AES decryption, offloading these tasks from the main CPU cores. D. One-Time Programmable (OTP) Fuses

Ensuring the code comes from a trusted source. Integrity: Ensuring the code has not been altered.

If the hashes match, the ISBC uses the public key to verify the digital signature of the ESBC. qoriq trust architecture 2.1 user guide

This guide explores the core components, boot process, and implementation strategies for Trust Architecture 2.1. 1. What is QorIQ Trust Architecture 2.1?

Generate your RSA keys. Keep the private key in a Hardware Security Module (HSM) or a highly secure, offline environment. Step 2: Create the Boot Image Integrity: Ensuring the code has not been altered

Set the physical pins or fuses to move the device from "Non-Secure" to "Secure" mode. In this mode, the CPU will refuse to boot any image that is not signed correctly. 6. Best Practices for Trust Architecture 2.1

Beyond signing (authentication), use the SEC engine to encrypt the bootloader image on the flash to protect your intellectual property. qoriq trust architecture 2.1 user guide

Once the software is finalized, you must blow the SRKH (System Root Key Hash) into the OTP fuses. Warning: This is irreversible. If you lose the private key associated with this hash, you will "brick" any future boards produced. Step 4: Enabling "Secure Boot" Mode
