Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
@Guillaume K, @Jocelyn RICARD Since my previous question on the same topic (see here) I have reviewed probably all the MCUboot/TF-M-based solutions available for ST MCUs. There are currently four options that I am aware of:TrustedFirmware-M (TF-M) us...
hi all,I am trying to implement a TCP echo device on STM32U585 controller. here the TCP/IP communication is over ethernet as well as USB (CDC ECM). The communication channel is protected using TLS encryption.here am using NetX stack as the TCP/IP sta...
Hi There, I am trying to get our product working using the SBSFU on our product. The latest problem I have is that the UART works when the application runs standalone - i.e. our code within the user app using the ST link, however, when...
Hello,I'm trying to run the X-CUBE-IOTA1 v3.0 on the B-U585I-IOT02A board, but after following the tutorial in UM2606 I get the following error when trying to send L2Sec Stream:What can be the reason of the pairing_stsafe result failing, please?Best ...
Hi,I'd like to ask if any example code for Azure IoT Hub group enrollment is available.I found examples for individual enrollment in X-CUBE-AZURE-v2-3-0 only.I try to follow the Just-in-time registration method and it fails when trying to connect to ...
I am adapting the NUCLEO-H753ZI single-slot project to work on a NUCLEO-H745ZI-Q board.My development environment is linux and I am using minicom for the ymodem upload.When flashed, the binary seems to function perfectly, but when I corrupt the image...
Hi experts,I need to implement the storage of a security key (upgradable) on STM32H7A3. After reading the example code of KMS under project B-L475E-IOT01A in x-cube-sbsfu, and a few posts in the forum (KSM support on STMH7 and 2-images-kms-port-to-s...
I want to use AES peripheral for encryption in ECB mode (256). I am able to encrypt and decrypt on the same MCU, but if I compare the encryption results, the HW peripheral has a different result than the SW library AES.c or encryption in Python - the...
Hi,I am currently using the M3_CryptoFW_RngHW_2_0_6.lib for MDK-ARM. However, I must adhere to this specific library version, and I now need it for IAR, meaning that the required library is M3_CryptoFW_RngHW_2_0_6.a. How can I obtain this version for...
Here is my attempt at background as I understand it... iROT is a ROM program in the STM32H563. It contains a P256 EC algorithm, and checks some section of FLASH that you define as a program for a signature, then jumps to it. The definition of the pro...
