Qoriq Trust Architecture 2.1 User Guide «High Speed»

Upon detecting a tamper event, the Security Monitor executes pre-configured policies. It can wipe secure RAM, zeroize keys, or force an immediate system reset. 5. Implementing Trust Architecture 2.1

The QorIQ Trust Architecture User Guide is a confidential document that requires a Non-Disclosure Agreement (NDA) with NXP to access:

: The ITS bit in the SFP is permanently "blown" to lock the system into a secure state, after which it will only boot signed code. Relevant Resources

User-defined external tamper detection circuitry must maintain the chip's tamper detect inputs at the voltage specified in the device's datasheet, with the security monitor reacting to a voltage drop in this signal.

# Example using NXP CST key formatting script ./cst --generate_hash --input oem_public_key.pem --output public_key_hash.bin Use code with caution. Upon detecting a tamper event, the Security Monitor

Secure debug is a critical feature that allows developers to debug Trust Architecture-enabled systems without compromising security. The Trust Architecture supports multiple secure debug modes with isolation from non-secure world debug modes.

IBR reads the public key from the image CSF, hashes it, and compares it against the hardware SFP fuses. Implementing Trust Architecture 2

Compared to previous iterations, Trust Architecture 2.1 introduces more robust provisioning and isolation methods:

The Qoriq Trust Architecture 2.1 is a security framework developed by Freescale Semiconductor (now part of NXP Semiconductors). It is designed to provide a comprehensive security solution for systems built on Qoriq processors, which are widely used in various applications, including industrial, automotive, and networking.

The SEC is a hardware accelerator that offloads cryptographic operations from the main CPU cores. In TA 2.1, it handles hashing, public key verification, and symmetric decryption during both the boot phase and runtime. 2. Hardware Security States

This article is based on publicly available documentation and community resources. For complete technical details, developers should consult the official QorIQ Trust Architecture 2.1 User Guide under NDA with NXP.

To configure Secure Boot, you must generate a cryptographic key pair and sign your boot images using NXP's Code Signing Tool (CST). Step 1: Generate the Cryptographic Key Pair
