Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
I am attempting to make a previously developed design run with Trustzone enabled. I have been unable to get the HSPI1 PSRAM to function.I've set the peripheral's GTZC's attributes to NSEC|NPRIV.I've set the appropriate GPIO pins' attributes to NSEC.I...
I am currently working with the STSAFE-A110 and I have noticed a significant lack of documentation for those who need to implement or understand the driver logic.For instance, when generating ECC asymmetric key pairs, the official datasheet mentions ...
Hello, everyone.Can the STM32F407VE encrypt multi-byte messages to maintain the confidentiality of messages between the host and client (stm32)? If so, what type of encryption can be run on this processor?Thank you:)
I'm working with the STM32U385/375 for a project, and have started my investigation into how to convert it to a secure root of trust application by working with the OEMiROT examples.In stock form it works well. The provisioning works, the update over...
Hi,I'm developing a secure boot application for STM32H563ZI microcontroller. I started with a very simple application following ST template code and tutorials like this one: https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_STM32CubeMX_OEM...
I've downloaded archive "en.STM32CubeExpansion_Crypto_v4.0.1.zip", now I'm trying to install it in STM32CubeMX with "From Local..." feature, but I'm getting error. How can I install the library in CubeMX?Thank you.
What I want to achieve:During startup all code is verified, starting with SMiRoT (as root-of-trust) then SMuRoT, then SecureManager then non-secure application.If the application has been modified (vberification fails) the startup shall end in system...
Hello, I have a problem with setting readout protection in the STM32L496 device in software. The protection is set to "BB". After setting and power on reset, the microcontroller seems to not work (it looks like as if it was "stuck up"). I connected t...
I try to enable the PCROP Feature on a STM32H753I am using the STM32CubeProgrammer and connect via ST-Link V2After connecting, I go to the "OB" page and set the PROT_AREA_END1 value to 0xFFF and activate the DMEP1Then I press the "Apply" button and t...
Hello ST team,I am studying the flash security mechanisms (RDP, WRP, PCROP) on STM32L476RG and I understand how to configure Option Bytes using STM32CubeProgrammer or firmware.What I am trying to understand is the hardware-level enforcement flow of O...
