Hi,I am doing a feasibility study for SBSFU on an STM32H750, specifically firmware encryption and authenticity check. I am using the XCUBE expansion pack v2.8.0.- Using prepareimage.py & modified keys.py along with default prebuild and postbuild.sh- ...
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...
Hi,we are experiencing an issue with the STM32G0B0 when RDP level 1 is enabled, following the steps below:Flash the device using J-LinkStart the device and let the application set RDP = 1Enter the STM32 ROM bootloader (via UART)Disable RDP protection...
I would like to implement a secure firmware update solution that will work in both an STM32G4A1 and an STM32U0 83. Different applications, but I would like to use the same basic bootloader and PC update application. Both would updated over USB. T...
I have the NUCLEO-H753ZI example running on my board. All works fine without the security features. When I enable both the SFU_MPU_PROTECT_ENABLE and SFU_IWDG_PROTECT_ENABLE. I keep having a watchdog when it tries to execute the firmware. I commented...
Can you help with new research on secure boot? I am a cyber security researcher at the University of Bristol in the UK. I would like to your views on Secure boot. My area of interest is developer-centred security, specifically in the issues that ...
Hello. I am experimenting with securing a STM32H503 using password authentication, which will ultimately be an automated process.I created a simple password for testing and created the password hash in board_password.bin and da_password.bin(just for...
I have legacy SBSFU based system running on an stm32f429 for a few years now, based on the STM32F413ZHT6 demo code that was present in the package. I am now interesting to using the KMS feature of SBSFU but after reading um2622 /seeing https://www.yo...
I am trying to integrate a very simple TouchGFX Application into the SBSFU (I only really need SB right now) application, on STM32U5A9J-DKI've switched out the Nonsecure application for mine, I've modified flash_layout to do primary only, no external...
I've been watching the MOOC - Security series and had some questions. There is a link in the info block to a forum for any questions, but the link no longer works. https://www.youtube.com/watch?v=g7ykhnmh7sAIs this the right place?I got to the end ...
