Security chip for Matter
We are developing this on st-cube-matter.We are using the STM32WB5MMG-DK evaluation board, but is there a recommended device for the security chip that stores the certificates for the DAC, NOC, etc.?

Resolved! Inconsistent SBSFU error for Header FW signature verification failure
I'm starting from the X-CUBE-SBSFU release v2.6.2, using the B-L475E-IOT01A - 2_Images_ExtFlash as a reference. I've done the minimum porting required to run this on an STM32L4A6 target.I'm seeing an inconsistent issue where the SBSFU boots up and a...
Resolved! Security Mechanisms in STM32H753ZI for Preventing Unauthorized Access and Modification
Does the STM32H753ZI microcontroller provide a built-in unique key or mechanism to ensure that the chip cannot be unlocked, and firmware cannot be flashed, read, or erased without the correct key, effectively preventing unauthorized access or modific...
Resolved! Is psa_generate_random() equivalent to HAL_RNG_GenerateRandomNumber()?
STM32H573 with Secure Manager provisioned, the non-secure app cannot access the RNG anymore. Will it be ok to use Secure Manager API psa_generate_random() to replace HAL_RNG_GenerateRandomNumber()?
SecureManagerAPI.chm content is empty
The file is under X-CUBE-SEC-M-H5_V1.2.0\Middlewares\ST\secure_manager_api; it can be opened without any error, but the right panel is always empty.
Resolved! ECC key decompression in X-CUBE-CRYPTOLIB
I am using the X-CUBE-CRYPTOLIB (V4.2.0) in a project for STM32F207.I am successfully able to generate ECC key pair using cmox_ecdsa_keyGen() and generate ECDSA signature using cmox_ecdsa_sign() but I am now needing to generate a shared secret using ...
Change target from STM32WL55JC to STM32WLE5C8 without CubeMX
Hello,I want to change target of BFU_2_Slots (1_Image_BFU, 1_Image_SECoreBin and also 1_Image_UserApp) from STM32CubeWL v1.3.0 (STM32Cube_FW_WL_V1.3.0/Projects/NUCLEO-WL55JC/Applications/BFU_2_Slots) from STM32WL55JC to STM32WLE5C8, but I do not know...
Resolved! STM32H573 Debug Authentification MCU Locked?
Hallo together,i`m working with the STM32H573I-DK EvalBoard to check if the Chip fits our project needs.I was working with the template STiROT_Appli from the STM32Cube_FW_H5_V1.3.0 Firmware. Full path to the template: STM32Cube_FW_H5_V1.3.0\Projects\...
Resolved! STM32L496ZG-NUCLEO-144 X-CUBE-SBSFU using USB_OTG_FS Virtual Com Port instead of YMODEM over UART
Hello everyone,Thank you for clicking this post. I am new to the community and ecosystem. Here's my task, I am trying to use the X-CUBE-SBSFU libraries to perform a secure firmware update procedure. I am using the STM32L496ZG-NUCLEO-144 board to test...
Resolved! How to access UID_BASE from non-secure app in STM32H573?
H5 has Secure Manager provisioned, and got exception when trying to access UID_BASE to retrieve device ID. #define UID_BASE (0x08FFF800UL) /*!< Unique device ID register base address */
