Qoriq Trust Architecture 2.1 User Guide Guide

Security requires heavy math, which is slow on general-purpose CPUs.

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

Detects glitching attacks meant to skip instructions. Frequency Monitoring: Detects clock-tampering attempts.

The NXP is a sophisticated, silicon-based security framework designed to protect embedded systems throughout their entire lifecycle. By establishing a hardware root of trust, it ensures that only validated software executes on the device and that sensitive data remains protected from both remote and physical attacks. Key Components of Trust Architecture 2.1

TA 2.1 defines several states:

The CSU allows developers to categorize peripherals into secure or non-secure zones. For example, an ethernet controller handling public network traffic can be restricted from accessing the memory regions allocated to the CAAM or internal secure RAM.

The processor powers on and begins executing from the internal Boot ROM. The Boot ROM reads the configuration fuses from the SFP to determine if Secure Boot is enabled.

The guide covers mechanisms to ensure the system hasn't been compromised while it is running.

# Generate a 4096-bit RSA Private Key openssl genrsa -out oem_private_key.pem 4096 # Extract the corresponding Public Key openssl rsa -pubout -in oem_private_key.pem -out oem_public_key.pem Use code with caution. Step 2: Create the Key Hash for Fuses qoriq trust architecture 2.1 user guide

On the screen, the malware—designated "SilentRot"—was trying to initiate a DMA (Direct Memory Access) transfer to pull the encryption keys from RAM.

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

The architecture is comprised of several integrated hardware blocks and software protocols that work in tandem to secure the platform:

Full debugging capabilities (use for development only). Security requires heavy math, which is slow on

TA 2.1 supports RSA 4K or ECC P-256. We will use RSA 4K as the default.

Internal Secure Boot Code (ISBC) & External Secure Boot Code (ESBC)

: The device checks the Intent to Secure (ITS) fuse. If set, the Internal Boot ROM takes control.
