Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Hello,I'm developing an application with OEMiRoT and trustzone for STM32H563.I'm getting a write protection error (WRPERR) when I try to erase a secure flash sector from secure code that is not protected neither by write protection or HDP. I'm using ...
I am looking for information that compares the security in an STM32U5 or similar with the PUF-based solutions used in competitor's processors. The problem is that "PUF" has a simple explanation that sounds good and a head-to-head analysis of the adv...
Hello everyone,I’m working on a project with Secure Manager on STM32H573IIK3Q using the STM32H573-DK board. I have followed the official tutorial from ST to make my application compatible with Secure Manager:https://wiki.st.com/stm32mcu/wiki/Security...
Hello,I'm currently working on a project using the STM32U5A5VJT6 processor, and I'm exploring the feasibility of implementing WireGuard in a bare-metal environment. I found one mention of WireGuard in this community post [link], however afaik it is a...
Hello,I am working on the X‑CUBE‑AZURE TFM_Azure_IoT example for the B‑U585I‑IOT02A board and would like to replace the default UART loader with CAN and USB loaders. While the non-secure loader boots and runs correctly, the non-secure interrupts for ...
We are currently in the early planning stages of developing a PCI PTS/SSF-compliant payment terminal and have selected the STM32U5 series as our target MCU due to its advanced security features (TrustZone, PCROP, HUK, etc.).To ensure we start on the ...
Dear community,where can I find the source code for this generated MX66UW1G45G_STM32H7S78-DK_XSPIM1-SFIx.stldr file?I need to load binary files on an sd/emmc flash passing through the OEMiRoT boot that loads the specific external loader I want to imp...
Hello,I am working with the STM32L476 and would like some clarification regarding the One-Time Programmable (OTP) area.From the reference manual, I understand that STM32L4 devices provide 1 KB of user OTP memory (128 double words). I would like to be...
I have created my secure boot demo project on STM32H563ZI using the link below.https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_STM32CubeMX_OEMiRoT_Boot_path_on_STM32H563During provisioning, the secure image is signed by the TPC (STM32Tru...
Our current product uses the STM32H533 microcontroller and password based Debug Authentication. We have a need to generate a large number of different DA passwords and corresponding OB Keys provisioning data. This is possible by creating our own tool...
