Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Does Secure Manager actually use USART1 when it comes up or is the initial serial output from the default app installed when I provision Secure Manager (SM)?This output, I mean================= General Infos ==========================Flash Layout con...
Hi,I am using the function STM32_AES_CBC_Encrypt from the ST library Crypto 3.1.0. I don't understand why this function doesn't give me an encrypted message which is a multiple of 64 bytes. For example, I would like to encrypt "thisisatest12345". Th...
Hi,I have been experimenting with secure boot on the STM32H573I-DK, but I can't perform a regression anymore.While adapting the example code (OEMiROT) to my own version, I am currently in the situation where the device is "provisioned" (0x2e), but I ...
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...
