Qoriq Trust Architecture 21 User Guide -

Run the CST utility to generate the RSA-2048 or RSA-4096 key pairs: ./cst --generate_keys crypto.cfg Use code with caution.

The NXP QorIQ Trust Architecture 2.1 is a robust hardware-based security framework designed for embedded systems. It safeguards high-performance networking, industrial, and aerospace processors against physical and logical attacks. This guide explains its core components, boot process, and implementation strategies. Core Components of Trust Architecture 2.1

: Initializes the SEC engine to validate the next boot stage. 2. On-Chip One-Time Programmable (OTP) Fuses Root Keys : Stores the SHA-256 hash of the public OEM keys.

[ Internal Boot ROM ] | v <-- Validates CSF using OEM Public Key Hash (OTP Fuses) [ Pre-Boot Loader (PBL) / U-Boot ] | v <-- Validates FIT Image Signature [ Linux Kernel & Device Tree ] | v <-- Validates Root Filesystem Integrity [ Secure User Space Application ] Phase 1: Initialization The processor powers up in a secure state. qoriq trust architecture 21 user guide

The architecture relies on four fundamental pillars to establish a trusted computing environment. Secure Boot (Hardware Root of Trust)

In production, JTAG access can be permanently disabled via fuses.

Securely stores and manages persistent secrets, such as the One-Time Programmable Master Key (OTPMK), which are never exposed to the software. Core Components Run the CST utility to generate the RSA-2048

Physical enclosure breaching (via dedicated tamper detection loops) Security State Machine and Zeroization

The architecture relies on a "Chain of Trust" that ensures every piece of code executed is verified and authorized.

Utilize OpenSSL or NXP’s Code Signing Tool (CST) to generate RSA or ECC key pairs. This guide explains its core components, boot process,

The primary operational manifestation of Trust Architecture 2.1 is the flow. Secure Boot ensures that only untampered, vendor-approved code runs on the hardware.
