Qoriq Trust Architecture 21 User Guide

Use the monotonic counters in the SNVS to implement a robust firmware revocation policy.

Keep your Trusted Computing Base (the code that must be secure for the system to be safe) as small as possible.

./cst --generate_hash --input srk_table.bin --output srk_hash.bin Use code with caution. Step 2: Read Current Fuse Status

To obtain the full text or document, you must typically follow these steps through the NXP Support Register with a Corporate Email:

TA 2.1 includes features to prevent unauthorized cloning during the manufacturing process. By using unique device secrets, developers can ensure that firmware intended for "Device A" cannot be copied and run on "Device B." Secure Debug qoriq trust architecture 21 user guide

If you are currently setting up your environment, let me know:

Generate a public/private key pair (typically RSA-2048 or RSA-4096).

Caution: Programming OTP fuses is irreversible. Double-check all values before execution.

The ISBC (typically a verified primary bootloader) assumes responsibility for the next layer. It uses the same infrastructure to validate the secondary bootloader (e.g., U-Boot or ARM Trusted Firmware), which in turn validates the Operating System kernel and root filesystem. 4. Key Management and Fuse Programming Use the monotonic counters in the SNVS to

The Fuse Processor Controlling Unit (FPCU) manages a bank of write-once electronic fuses (eFuses). These fuses store permanent configuration data that dictates the security posture of the chip. Key fuse registers include:

For each boot stage (u-boot, OS):

If you can tell me (e.g., T1040, LS1046A), I can help you find the exact documentation, tools, and fiptool configuration for your project. INTRODUCTION TO QORIQ TRUST ARCHITECTURE

: Provides the foundation for all security operations, including secure boot and secret key protection.

AES-128, AES-256, and 3DES for data-at-rest and data-in-motion encryption.

Program the hash of the public key into the SoC's One-Time Programmable (OTP) fuses. This commits the device to the Trust Architecture. Phase 2: Image Preparation

If valid, control is passed to the next stage (External Secure Boot Code - ESBC). 4. Implementation Steps: Setting Up Trust Architecture
