Qoriq Trust Architecture 2.1 User Guide __top__ <QUICK>

Using the CST, wrap your bootloader (e.g., u-boot.bin ) with a . This header contains the public key, the signature of the image, and the load addresses. Step 3: Fuse Blowing (Development vs. Production)

The QorIQ Trust Architecture 2.1 is a powerful defense mechanism against physical and remote exploits. By establishing a hardware-rooted chain of trust, developers can ensure that their QorIQ-based systems remain resilient in hostile environments. While the initial setup of keys and fuses requires precision, the result is a system that is virtually impossible to subvert without the authorized private keys.

The ISBC reads the Command Sequence Control (CSC) and the header of the external bootloader. It compares the hash of the public key in the header against the hash stored in the hardware fuses. 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)

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 Using the CST, wrap your bootloader (e

Implement logging within your OS to monitor for "Security Violations" reported by the SEC block during runtime. Conclusion

Set the physical pins or fuses to move the device from "Non-Secure" to "Secure" mode. In this mode, the CPU will refuse to boot any image that is not signed correctly. 6. Best Practices for Trust Architecture 2.1 Production) The QorIQ Trust Architecture 2

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
