Qoriq Trust Architecture 21 User Guide ✨

Controls the locking down of hardware debug ports (JTAG). 3. Security Engine (SEC 5.0)

Here is a condensed implementation flow found in the guide for enabling secure boot on a LS1046A or P4080.

The RTC is a TA 2.1 enhancement over earlier versions. It monitors critical code regions (e.g., interrupt vectors, secure monitor) periodically or via bus watchpoints. If a region is modified unexpectedly, the RTC can: qoriq trust architecture 21 user guide

: The default factory setting where all development, debugging, and testing occur without cryptographic checks. Controls the locking down of hardware debug ports (JTAG)

The ISBC loads the external software (e.g., U-Boot) and its signature, validating it against the stored public key.

TA 2.1 includes hardware engines that act as sentries while the OS is running.

By embedding cryptographic accelerators and state machines directly into the silicon, version 2.1 ensures that security checks happen at hardware speed, minimizing the performance overhead traditionally associated with software-based security layers. 2. Core Security Pillars

: Trust Architecture 2.1 supports key revocation. If one of your private production keys is compromised, you can program a fuse to invalidate that specific key index, forcing the system to rely on alternative keys in your SRK table.
