Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Hi,While using the STM32Cube_FW_H5_V1.1.1 repository to explore secure boot on the STM32H5, I saw that the configuration file to generate OEMiRoT_Data.obk is missing. As I want to use my own keys and certificates for the OEMiRoT example application, ...
So, I want to modify provisioning.bat and/or XML files to create an SFI that contains our developed non-secure app instead of default one, Secure Manager, and the various (especially DA one) OBKs.This will then be downloaded into factory-fresh (only ...
Hello,RM0444.Rev5 page 98 says that it is possible to reset it only when:• RDP is set to Level 0, or• RDP is set to Level 1, while Level 0 is requested and a full mass-erase is performed.I supposed that if RDP is changed from level1 to level0 then th...
Hello all,I have a question about additional MPU protection provided by enabling SFU_MPU_PROTECT_ENABLE.What are the main benefits of that?How much "protection value" do we miss if it's disabled?
Hi all,I am using STM32F769I DISCO Board, STM32 CUBEIDE,X-CUBE-SBSFU 2.6.2 , WINDOWS Environment for checking new features in security i.e. secure bootloader.I am newbie to this topic and I have followed compilation procedure as per the readme file,...
Hello,please I need a confirmation about RDP level2 and WRP combination on stm32g031 chip.Based on RM0444.Rev5 Table 19, if I use my own bootloader and I write-protect the flash sectors, I have to avoid activating RDP level2 or I'll loose the opportu...
I am building a secure bootloader on the STM32H755, but I've bricked a couple of boards now trying to get the secure areas working.I intended to use a "recovery" function on a button press to do a mass erase with protection removal. Then I can test e...
Hi all,One small doubt on the tamper configuration, is it possible to configure both active and Passive tamper in the Same project/API, or both should be in different project/API. why this doubt is as Seed is not required for Passive tamper, so does...
Hi,Where can I find a documentation for the version 4 of X-CUBE-CRYPTOLIB ?Regards,Fred.
Hello As in the title, for my project I'd like to know exactly what is the maximum storage capability/size of the device NV memory.The TPM used is ST33TPHF2XI2C.I wasn't able to find anything in ST documentation (datasheet, application notes).Waiting...
