Trust Architecture 2.1 User Guide: Qoriq

To utilize Trust Architecture 2.1, developers need the provided by NXP. Requirements: Private/Public Key Pair: Usually RSA-2048 or RSA-4096.

Implement logging within your OS to monitor for "Security Violations" reported by the SEC block during runtime. Conclusion qoriq trust architecture 2.1 user guide

To implement the 2.1 architecture, several hardware modules work in tandem: A. Internal Secure Boot Code (ISBC) To utilize Trust Architecture 2

The ISBC is the first code executed by the processor upon power-on. It is stored in immutable ROM. Its primary job is to validate the next stage of the bootloader (the ESBC). B. External Secure Boot Code (ESBC) Conclusion To implement the 2

Once the software is finalized, you must blow the SRKH (System Root Key Hash) into the OTP fuses. Warning: This is irreversible. If you lose the private key associated with this hash, you will "brick" any future boards produced. Step 4: Enabling "Secure Boot" Mode

The SoC contains a fuse processor. Once "blown," these fuses permanently store the public key hashes (OTPMK) and security configurations. This makes the security settings immutable. 3. The Secure Boot Sequence
