: Offloads intensive security tasks such as encryption, hashing, and signing to dedicated hardware components. Tamper Detection

Before shipping a product, the "hashes" of your public keys must be burned into the SoC’s fuses. This is a one-time operation. It is highly recommended to use a process during development to test fuse settings before they are permanently locked. C. Runtime Security qoriq trust architecture 2.1 user guide

For more information on the Qoriq Trust Architecture 2.1, refer to the following resources:

Secure boot ensures that the bootloader, kernel, and applications are authentic before execution. The first code executed, which cannot be modified. It is highly recommended to use a process

: The ITS bit in the SFP is permanently "blown" to lock the system into a secure state, after which it will only boot signed code. Relevant Resources

To prepare a board for secure boot, an OEM must perform several critical steps: The first code executed, which cannot be modified

Set the "Internal Trusted System" (ITS) bit in the SFP to enable the authentication process at boot.

The (also known as Layerscape Security) is the foundation of hardware-based security for modern embedded systems. As networking and industrial applications face increasingly sophisticated threats, version 2.1 provides the cryptographic "root of trust" required to protect data, identity, and firmware.
