Yes, TF-M runs in the secure domain, and the app in the non-secure domain. It replaces SPM.

I can't use TF-M because my project is now divided into two parts, secure and non-secure. I need to make work the cryptography in the non-secure part!

Hi,

I recommend using TF-M if you are going to use the cryptocell from the non secure domain. Otherwise you will have to implement your own secure services for SPM.

[quote user=""]-This guide https://infocenter.nordicsemi.com/index.jsp?topic=%2Fps_nrf9160%2Fcryptocell.html&cp=2_0_0_5_0 explain to me how this encryption/decryption works or it is also an alternative for the code that I found?[/quote]

This is the documentation of the cryptocell module used to accelerate crypto operations in HW. TF-M uses this module by default.
