: Provides OEM-controlled trade-offs between debug visibility and sensitivity to physical tampering. The Technical Edge: TA 2.1 Improvements
: These include the chip’s OTPMK, optional ZMK, and any code, factory-installed private asymmetric keys, and pre-shared symmetric keys encrypted by the OTPMK or ZMK and stored to nonvolatile memory. The Trust Architecture ensures these secrets survive resets but remain protected from extraction. qoriq trust architecture 2.1 user guide
