Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Hello,I'm looking for some clarification over how the PCROP area can be used. The user manual for STM32L471 states that code in this area can be executed but that data at flash in this area cannot be read. Does this mean if I put a decryption algo...
I am trying to integrate a very simple TouchGFX Application into the SBSFU (I only really need SB right now) application, on STM32U5A9J-DKI've switched out the Nonsecure application for mine, I've modified flash_layout to do primary only, no external...
Good morning everyone,I need to apply the "Closed" product state to my device using the STM32H573VI.I don't need TrustZone enabled and want to use a password for debug authentication.I wanted to perform the operation via "code" using the HALs, but on...
I'm working on a project which is being ported over to be TrustZone aware, part of this project makes use of an OCTOSPI configured in memory mapped mode for file access. Base settings come from the IOC however the memory mapping is executed in source...
Hello. I am experimenting with securing a STM32H503 using password authentication, which will ultimately be an automated process.I created a simple password for testing and created the password hash in board_password.bin and da_password.bin(just for...
I have exported X509 certificate from STM32H573I-DK board, and checked how it is organised.The certificate was issued by "ST CA 01 for STM32 Initial Attestation".I would like to verify whether it is truely signed by ST's upper-level certificate.Wher...
Hi ST team,I am using STM32U5G9 in my project. It would need simple firmware update feature and the image would be received by UART from a zigbee module.I have read UM2851 and AN5447 application notes and check the SBSFU example in STM32CubeU5 packag...
We need to develop an offline programmer to program the STM32H562VIT. The product state need to be changed to Closed with an OBK file programmed. The OBK data only in HDPL1.We can't simply use the RSS to program the OBK like STM32Cubeprogrammer. We c...
STM32 H573 TrustZone Enabled question. I'm executing the STM32 H573 example for TrustZone Enabled (OEMiROT, Secure, and Non Secure Apps). I know the OEMiROT and Non Secure App prints out and logs info, but I want to be able to do that in the Secure ...
Hello, I am looking for guidance regarding the STM32H533 MCU, specifically in the area of secure and non-secure memory management.Could you please let me know if there is a dedicated application note that explains how to store and manage encrypted ke...
