Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Hi, we are developping a projet with TFM activated on STM32U585 device (by the way, we don't really need the full TFM but at least Secure boot and SBSFU). We would want to declare a Flash page to store some configurations parameters, so we created a ...
Need assistance on generation of the ECC key pair using crypto library. Can you guide on how to link the required .a files to the project tool (IAR embedded workbench) so that the function declarations present in .h files without .c files will execut...

STM32U585 When TrustZone is enabled, X-CUBE-CRYPTOLIB produces incorrect SHA256 hash values.Additionally, mbedTLS generates incorrect public keys when creating ECDSA key pairs, and this issue is 100% reproducible.Neither hardware acceleration is enab...
HiI have a design using STM32H523 and I've managed to ensure that my firmware switches PRODUCT_STATE to 'Closed', and sets a valid debug password, the first time it runs. This works well.In the Flash I have a bootloader, application, and configuratio...
Hello, I am asking for help from the community. My application is completely written, but I can't set read protection. I tried to do all the steps in this guide, but it led to bricking one of my boards. The second board is still in product state = 17...
Hello,I am currently working with the STM32CubeN6 MCU Package and I noticed something surprising:For NUCLEO-N657X0-Q templates like Template_FSBL_LRUN and Template_FSBL_XIP, STM32CubeIDE projects are provided directly (under /STM32CubeIDE/).For Temp...
Colleagues.I recently implemented Proprietary code readout protection (PCROP) according to AN4758 on the STM32G473CEU MCU in IAR v.9.50.1. The project I was protecting was quite large and did not fit into one flash bank. As soon as the project no lon...
Hello,I have a problem with the operation of my firmware in "closed" state of PRODUCT_STATE. When my device is in "open" mode (ED code) my firmware works perfectly fine, but when i do provisioning procedure and change state to closed (72 code), my fi...
Hello everyone,My team and I are working with a custom board based on the STM32WB55RG. Due to limited pin availability, we need to use USB as a virtual COM port for serial communication. We successfully configured the USB Virtual COM and were able to...
