Hello,
I am using X-CUBE SBSFU for an application running on STM32H750 mcu.
The user application is running from QSPI, and I want to encrypt/decrypt some data that will be stored into an external EEPROM.
To do this I would like to use an AES algorithm and I would like to store the crypto key in a secure area.
In this regard it is not clear to me whether it is possible to store selected data/code in secure flash that can be accessed through the call gate feature by the user application.
I will use encrypted firmware update, so it would also be fine to access the firmware encryption AES private key or encryption functions using that key.
Thanks to anyone who could help me to put some light on this topic,
Ivan
