Qoriq Trust Architecture 2.1 User Guide -

: Securely manages and stores cryptographic keys, preventing them from being exposed to untrusted software. NXP Community Document Accessibility QorIQ Trust Architecture 2.1 User Guide is considered a confidential document

The is a confidential, technical document essential for developers implementing secure boot and advanced hardware security on NXP's multi-core Layerscape and QorIQ processors. Because it contains proprietary hardware specifications, it is typically provided by NXP only under a Non-Disclosure Agreement (NDA) . Key Components of Trust Architecture 2.1

A: If an image fails signature verification, the ISBC will attempt to load an alternate image if one is available. If no valid image is found, the system may fail to boot or enter a recovery mode.

The foundation of QorIQ TA 2.1 security relies on a cryptographic Chain of Trust. If any link in this chain fails verification, the system halts execution to prevent compromise.

The architecture is designed as an "opt-in" scheme, allowing OEMs to balance security needs with performance and debug requirements. Key features include: NXP Community Secure Boot : Establishes a hardware Root of Trust

Support for SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512.

A SHA-256 hash of the SRK table that is permanently burned into the device's OTP fuses. The IBR compares this fuse value against the boot image key to verify its authenticity. Image Validation Layout

Often caused by missing or misconfigured clock gates or device tree entries for the security engine inside the Linux kernel. : Securely manages and stores cryptographic keys, preventing

Do not share the same Super Root Key across different product lines. If one product is compromised, unique keys isolate the damage.

The system booted successfully with trusted, signed code. All security features are active.

The SEC engine includes a Run-Time Integrity Checker that monitors system memory in the background. It continuously hashes designated blocks of memory (such as kernel text segments) and compares them against known baseline values to detect run-time memory corruption or rootkit injections.

Based on the Trust Architecture 2.1 guidelines, here is the flow for implementing secure boot on a QorIQ platform: Key Components of Trust Architecture 2

If Secure Boot is enabled, the Boot ROM loads the Embedded Secure Boot Loader (ESBC) image from the boot source (such as SPI Nor Flash, eMMC, or SD).

This guide provides an overview of the key components, principles, and implementation steps described in the . 1. Introduction to QorIQ Trust Architecture 2.1
