Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
I'm trying to understand how the HDPL1 is calculated based on an OBK file.I have dumped the contents of HDPL1 / 0x0BDF0100 and can see that for a 16 length password, I have 96 bytes written, as follows0x0BFD0100 to 0x0BFD0120, unknown calc, how is th...
I used STM32F103 in a mix configuration of bare-metal&HAL supplied by STM32CubeMX. I'm not sure ST can provide the documentation that can be referenced to generate the SBOM for cybersecurity purpose. Is there any recommended tool to scan the firmware...
I've got an STM32U385 on a custom board that is unresponsive.The software is based on the OEMiROT trustzone example.The sequence of events that lead to this, as nearly as I can remember were:1.) Set up the device with provision.bat, with RDP level 2....
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- ...
Hi, using STM32 Cube Programmer and STM32 Trusted Package Creator W2.21, I was unable to detect the HSM card, getting error 0x88000002. I had to downgrade to V2.14, as mentionned in several posts to get it detected successfully.I use HID Omnikey 3121...
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...
We have a query regarding STM32U375 PKA peripheral.As per datasheet, the peripheral is available for this variant. Under the "STM32Cube/Repository/STM32Cube_FW_U3_V1.2.1/Drivers/STM32U3xx_HAL_Driver/" we can also see that stm32u3xx_hal_pka.c and stm3...
Hi,based on the ST example where the 640kB RAM is splitted into 2 * 320kB for secure/non-secure application, I want to change this to 32kB/608kB for secure/non-secure app. After modification of the linker files for the secure/non-secure app, the non-...
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...
