The QorIQ Trust Architecture 2.1 follows a chain of trust model: The CPU starts in a "Check" state.
Protecting sensitive data and IP via encryption. qoriq trust architecture 2.1 user guide
The SEC block handles high-speed cryptographic operations, including RSA signature verification and AES decryption, offloading these tasks from the main CPU cores. D. One-Time Programmable (OTP) Fuses 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 This makes the security settings immutable
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.
