: 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.

A crucial first note: The official QorIQ Trust Architecture 2.1 User Guide is a restricted document. It is not available for public download from the NXP website. To obtain it, you must have a valid Non-Disclosure Agreement (NDA) in place with NXP. You can request access by contacting your local NXP field applications engineer (FAE) or sales representative and providing the necessary NDA information.

Once the ESBC is validated, it continues the validation process for the next stage (e.g., operating system kernel), establishing a full chain of trust. 2.2. Trust 2.0+ Features (Primary & Alternate Image)

Zeroizable master keys that wipe automatically upon a detected tamper event. 4. The Secure Boot Sequence

While the official user guide is restricted, the (Document Number: LS1012ARM, Rev. 1, 01/2018) is a publicly available document that provides an excellent, detailed overview of the architecture. Chapter 29, "Secure Boot and Trust Architecture 2.1," is the most valuable resource for developers seeking in-depth technical information on the Trust Architecture 2.1.
