Hi @victory
To better understand the Secure Boot we provide an application note including demo projects which explains all the steps in detail. It can be downloaded from:
S32K3 Microcontrollers for Automotive General Purpose
Application note can be found here:
Documentation -> Secure Files -> Secure Boot Application note v0.1.1.0 (AN744511)
Associated demo project can be downloaded here:
Design Resources -> Software -> Secure Files -> SecureBootAppNoteDemo (SW745310)
Also, you can refer to S32K3 MCUs for General Purpose HSE Demo Examples. These projects provide different use-case scenarios and examples to showcase the capabilities of the HSE FW in different devices. The current implementation of the Demo Application showcases examples covering the following areas for a FULL MEMORY HSE configuration (AB SWAP is still on testing phase):
- Symmetric Algorithms: Aes encryption, Aes decryption, CMAC generation, CMAC verification
- Asymmetric Algorithms: ECC ECDSA
- Secure Boot: Basic Secure Boot, Advanced Secure Boot, SHE-based Secure Boot
- Key Management: Session Keys, NVM Key update
- Device Configuration: HSE installation (FULL_MEM and AB_SWAP), HSE update (FULL_MEM and AB_SWAP), sBAF update, Key Catalog Formating, ADKP provisioning, Life Cycle Advancement, Secure Debug selection (static or dynamic)
