Hello,I am using the Nucleo-STM32F411RE development board and require support for cryptographic functions, particularly ECC NIST P-256, MAC, etc, for my development use cases.To achieve this, I downloaded the X-CUBE-CRYPTOLIB v4.3.0 package as it was...
Hello, I am trying to adapt the H753xx SBSFU implementation to the H745xx dual core board.I have so far configured a second slot by creating a second MPU region of 1KB to protect the header of the second slot, as well as changing the security checks ...
Hi,I am struggling to get `HAL_PKA_ECCCompleteAddition` implemented correctly, that is, if I'm comparing the projective coordinates with a reference implementation, the results don't match. Same goes for converting the projective coordinates back to ...
Hi,I try to use PKA for some ECDSA computation. For this purpose I needed to use PKA block. However, in SR register, I never get INITOK bit set. I am working with TrustZone enabled. So, STiRoT is executed before my program.After investigation, I've s...
Title edited to be more descriptive than just "USB"HI,I Need help, My application Requires Firmware updates using USB DFU Mode, and planning to make a custom Pc software that updates code using USB. How can I Make sure that only my Pc software shoul...
Hi,I'm currently experimenting with the decryption of custom data provisioned into the OBKeys storage with hardware encryption enabled.I've successfully provisioned the data without encryption and read it back intact. With encryption enabled, I see ...
How can we map HDPL levels to ST boot/ User Boot / User secure app/ user unsecure app in STM32H573 controller ? In user flash if I want to place my OEM ROT , OEM uROT, Secure App and Unsecure App, How do I map each HDPL level to corresponding boot or...
I tried to provision Secure Manager 1.2 to my DK board, and got the following error messages in the provisioning.log:2024-11-10 15:49:30,796 - root - DEBUG - Error: SFI command is not supported for the current device configuration using STLINK interf...
I am encountering an issue in the development of the TrustZone application related to the UART in secure non-privileged mode.I want to switch to non-privileged mode when in secure and privileged mode. This transition works correctly. However, I have ...
I have finally managed to get the SBSFU to work on my STM32F4-Discovery board. I've been working on this over the past month until I figured it out and got it to work. For some reason, I couldn't get the 2_Image version to work on my hardware. I bel...
