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...
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...
At present, as of the last Hal version as far as I know, obk cannot be used in a non trust zone project.FLASH_TYPEPROGRAM_QUADWORD_OBK fails because the NS bits aren't set, among other issues.Is this by design, IE obk can't be used by non TZ, or is t...
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'm working with the STM32U385/375 for a project, and have started my investigation into how to convert it to a secure root of trust application by working with the OEMiROT examples.In stock form it works well. The provisioning works, the update over...
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.I have tested the firmware installation using ECDSA signature without encryption.However,...
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 ...
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 ...
I am working with the STM32U585RIT6 and need to implement a secure firmware update. In my application code, I don’t want to handle flash management or low-level update logic. I only want to generate a secure binary file and perform the update.I revie...
