I need to add the security and encryption to my firmware for the STM32L432KB MCU.

Please suggest me that how do It or develop it.

If you want at least some security then don't do it yourself, cryptography is hard, just throwing in AES-256 (in what mode of operation? what about authentication? what about side-channel attacks? etc..) without understanding cryptography is basically useless.

So, hire a professional or use something ready, like OpenBLT, or mcuboot.

Hi @K_P_D​ ,

I invite you to use the crypto library package delivered by ST.

Below the link to cryptolibrary of ST.
