Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Hi,In the past we've always produced 'release' firmware for STM32F4 which checks the RDP level (memory read / debug protection) at boot up, and ensures it's automatically set to RDP1 (read protection enabled). This ensures that our code can't be easi...
Hi Team,I am new to SBSFU, and our team requires two image examples. To reduce boot time, I need to eliminate the complete swap region, and I am currently working on this.I will flash the SBSFU binary, including only the SBSFU application, using the ...
Hello,I am using the Nucleo-STM32F411RE development board and require support for cryptographic functions, particularly ECC Point Generation.input: w0, N output: Y, y Begin generate random scalar y on chosen curve Y=y×G+w0×N (G as defined NIST P-256...
Hi,I've tested freertos when trustzone is enabled, the freeRTOS can work.I've tested PSA API in "TFM_Appli\NonSecure" when freertos not used, also can work.When I try to access PSA API in "TFM_Appli\NonSecure", when freertos is used, it will trigger ...
After the build process for the project, I get a file.bin that I want to encrypt to be protected and decrypted in my chip via the bootloader. How is this done, knowing that I use stm32 cube ide?
Hello,I have successfully executed the default OEMiROT and Application projects in STM32CubeH5\Projects\NUCLEO-H563ZI\ on our prototype board based on STM32H563 1MB variant. Slight adaptations were needed for which I got plenty of support in this thr...
Hi everyone,We're working with STiROT and TrustZone on an STM32H5 (NUCLEO-H533RE), and during the provisioning process we generate the STiRoT_Config.obk file from the STiRoT_Config.xml using the Trusted Package Creator (TPC).Our question is whether t...
When I use mbedtls on my STM32U585 core board without enabling hardware acceleration, it works fine. However, when I follow the instructions in some posts and copy examples, such as the rsa_alt from SBSFU under STM32U5Cube, many errors appear, and it...
Hi,I am trying to get the OEMiROT example projects running on STM32H563 from "STM32CubeH5\Projects\NUCLEO-H563ZI\Applications\ROT". The provision.bat script fails after writing option bytes (probably after enabling TZ) and tries to reconnect to the M...
Hi, I have a firmware I wan't to give already flashed protected by PCROP to a customer. Insidie my firmware I use some standart library functions line strlen(), vsprintf and some HAL functions to manage peripherals.What is the best way to call these ...
