Qoriq: Trust Architecture 2.1 User Guide [upd]

: Using components like the PAMU (Peripheral Access Management Unit) to protect memory and resources from unauthorized access.

The most critical function of TA 2.1 is establishing a "Chain of Trust" (CoT). This ensures that only authenticated software signed by you, the developer, can run on the device. The process is often referred to as secure boot . qoriq trust architecture 2.1 user guide

# Example: Generating a 2048-bit RSA private key using OpenSSL openssl genrsa -out srk_private_key.pem 2048 openssl rsa -pubout -in srk_private_key.pem -out srk_public_key.pem Use code with caution. Step 2: Creating the Command Sequence File (CSF) : Using components like the PAMU (Peripheral Access

: 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 The process is often referred to as secure boot

Upon reset, the ROM code checks the fuses. If HAB is enabled, the ROM code uses the stored key hash to verify the signature of the PBL. If the verification fails, the system fails secure (i.e., it won't boot). 4. Debug and Tamper Protection
