User Guide | Qoriq Trust Architecture 21

In an era where cybersecurity threats are escalating, hardware-based security solutions have become critical for protecting embedded systems. This paper provides an overview of NXP Semiconductor’s Qoriq Trust Architecture (QTA) 21, a robust security framework designed for Qoriq Power Architecture and Qoriq 2- and 4-bit processors. Targeted at developers and system architects, this guide outlines QTA-21’s key features, technical architecture, use cases, and best practices for implementation.

The QorIQ Trust Architecture 21 (TA21) is a security framework integrated into NXP’s QorIQ processors to establish a hardware-rooted chain of trust for embedded and edge computing systems. Its primary purpose is to protect system integrity, confidentiality, and authenticity from power-up through runtime, addressing threats across software, firmware, and hardware layers. A user guide for TA21 helps system designers, firmware engineers, and integrators understand the architecture’s components, configuration options, and recommended workflows to build secure platforms.

Embedded systems frequently rely on accurate timekeeping to validate security certificates and software logs. The SRTC provides a tamper-resistant time source that maintains synchronization via a backup battery, resisting malicious attempts to roll back system time.

The QorIQ Trust Architecture 2.1 User Guide provides essential technical details for implementing silicon-based security, such as Secure Boot and ARM TrustZone, on NXP Layerscape processors. It is a critical, NDA-protected document that enables advanced features like hardware root of trust and runtime integrity checking. For more details, visit NXP Community .

If any signature fails, the processor enters a non-recoverable error state or loops in reset. There is no fallback to insecure code. In an era where cybersecurity threats are escalating,

To utilize the Trust Architecture, developers use a , which is part of NXP's QorIQ Layerscape Secure Platform. This tool is used to:

This guide provides an overview of the architecture's core functions, its key components, and the steps required to implement a secure boot sequence. Key Capabilities of Trust Architecture 2.1 The QorIQ Trust Architecture 21 (TA21) is a

A key distinction of version 2.1 from its predecessors is the integration of Arm's TrustZone technology, creating what is specifically called the .

NXP is likely to incorporate advancements like:
