Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Dear,I am writing to inquire about the inclusion of a validity period in the debug authentication certificates used with the STM32H7S3 microcontroller.My project requires that the debug access certificates I provision have a limited, defined lifespan...
Hi,We are using SBSFU and FreeRTOS in STM32H755xI. We are planning to use Zephyr RTOS in STM32H755xI. Can I use SBSFU bootloader in Zephyr RTOS?--Muthukrishnan
Hello Support Team,for testing purposes i am using the H533NucleoBoard. I can load my firmware into the MCU and the firmware is running as expected. I want use the final product in ProductionState: closed.The problem is, the firmware isn't running an...
Hi everyone,I have a question regarding SFI Option Bytes for the STM32H753ZI (Nucleo-H753ZI).Question:Which option bytes should I pick, since there are a lot of different combinations available: 1. Generated by TrustedPackageCreator: FLASH_OPTSR_PRG,...
Dear STMicroelectronics Community members,I am currently evaluating STM32 microcontrollers for a project that requires strong cryptographic capabilities. Our goal is to implement hybrid encryption, meaning we need hardware support for both symmetric ...
HiI am trying to perform a secure boot implementation in STM32F439ZIT6. The datasheet shows that, there is Hash, RNG, AECS and TDES. Can I perform secure boot functionality using only STM32F439ZIT6 without using any external chip and if so, are there...
Hello,I am working with Nucleo-STM32U385RG to implement the Root of Trust (Secure Boot) feature, following the wiki guide: https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_OEMiRoT_on_STM32U3My test environment is STM32Cube_FW_U3_V1.2.0.Du...
All the provided examples are using USART YMODEM to transfer data. I know, that it really doesn't matter what kind of protocol you use as long as image is placed in a correct place in the memory, but I wonder if I can use DFU feature to update firmwa...
Hello,I am trying to configure the secure memory in Secure Protection Bank 1 of options bytes section and for this I have followed the STM32 MOOC tutorial to understand the concept of using secure boot code. But I am facing issues as the base address...
Hello,We are working on an STM32F469/79-based device that uses SBSFU, which we are seeking to modify to use the STSAFE-A120 to perform the authentication and decryption algorithms.Section 2.7 of the STSAFE-A120 datasheet includes that the STSAFE-A120...
