Qoriq Trust Architecture 2.1 User Guide Info

The QorIQ Trust Architecture 2.1 (often associated with NXP Power Architecture processors like the T-series and LS-series) is a robust security framework designed to establish a "Root of Trust" in embedded networking and aerospace/defense systems.

When reading the User Guide, you will encounter a complex ecosystem of hardware and software components. Here are the most interesting and critical features explained: qoriq trust architecture 2.1 user guide

1. The Hardware Root of Trust (RoT)

This is the foundational feature. Unlike software security, which can be patched or bypassed, the Trust Architecture relies on immutable hardware. The QorIQ Trust Architecture 2

• Secure Boot: When the processor powers on, it doesn't just start the OS. It verifies the signature of the initial bootloader code (RCW/PBI) using on-chip public keys.
• OTP (One-Time Programmable) Memory: The guide details how to blow fuses (physically or virtually) to store cryptographic keys and hashes. Once these fuses are blown, the keys cannot be changed, creating a permanent hardware identity for the chip.

Step 1: Generate the Super Root Key (SRK) Table

The SRK is not a single key but a table of up to 4 public keys. You generate 4 key pairs: SRK1, SRK2, SRK3, SRK4. Secure Boot: When the processor powers on, it

cd cst/keys
openssl ecparam -name prime256v1 -genkey -noout -out srk1_256.pem   # for ECC
# OR for RSA 4K:
openssl genrsa -out srk1_4096.pem 4096
openssl rsa -pubout -in srk1_4096.pem -out srk1_4096_pub.pem
# Repeat for srk2, srk3, srk4

Then generate the SRK table (hash + public keys):

../cst --gen-srk-table --srk-list srk1_4096.pem,srk2_4096.pem,srk3_4096.pem,srk4_4096.pem --out srk_table.bin

This outputs srk_table.bin and also calculates the SRK Hash (displayed on console). Guard that hash with your life—it’s the fingerprint of your root of trust.

On host (offline)

./cst --sign-debug-challenge --challenge 0xABCD1234... --key srk1_4096.pem --out response.bin
