I'm curious about the firewall, and want to know why firewall can improve the security level. It's easy to understand page 65 of UM2262, f1(), f2(), f3() can only be called from outside through call gate, my question is why it's more secure than call...
We are working on developing a host-module that requires two-way device authenticationThe controller we are planning to use is the STM32WL55 Series.We have the following Queries.1) Does STM32WL55 has a functionality to locally generate a certificate ...
1. If in RDP Level 1, can the SRAM be read?2. If starting in RDP Level 1 and transitioning to RDP Level 0, is the SRAM erased?3. Can the contents of SRAM be readout after the transition from RDP Level 1 to RDP Level 0? Thanks.
In the STM32H573-DK BOARD,How to store the public and private key in secure part ?
The Issue When my bootloader jumps to the application all `AES_ECB_Encrypt_XXX` incorrectly encrypt/decrypt the data. Once the application fails to initialize too many times it will reboot due to watchdog and the ncrypt/decrypt will continue to fail ...
Hello all,Another question from SBSFU series.I'm wondering what are the available ways to clear option bytes?The option I was using so far was simply STM32CubeProgrammer GUI, but what if we don't have ST-Link on board and we have to rely on something...
Hi, need support. send_msg() is a secure area message of TF-M and I am calling it in non secure area via secure_nsc API.What I am observing here is that I am not able to call this function in _tx_initialize_kernel_enter() function after the call to T...
hello I'm using a STM32H573-DK board for engineering samples. so. I'm run a example this link but provisioning.bat files does not run at 'Step 3 : Provisioning'How to fix this problem?
Hello all,Kindly guide us how to resolve the following issue or share the sample code,We are using MCU STM32U585QII6QTR. In this TrustZone is not enabled.We are trying to change the RDP level from 0 to level 1 and from level 1 to level 0 from softwar...
Hi,I need to implement things that are required to implement secure boot & secure software update STM32 H733 Microcontrollers. Trying to understand from the beginner perspective, though I have the Cube package downloaded from the st website, still li...
