Hi ST team,I am trying to develop a secure bootloader and firmware update solution for STM32H735 MCU. I was looking at ST's implementations, SBSFU legacy and SBSFU by MCUboot. Could you give me some guidance, which would be the better choice to start...
Hi,I'm using two STM32WLE5 LoRa as TX and RX and added AES-ECB Encryption with Hardware Accelerator in the TX side and receive and decrypt it in RX side with the same Key. Now I want to change the TX module and want to implement same logic of AES Enc...
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 using the link below to select boot path and do secure boot device provisioning for my STM32H563 board:https://wiki.st.com/stm32mcu/wiki/Security:How_to_start_with_STM32CubeMX_OEMiRoT_Boot_path_on_STM32H563Boot path is configured as follows:I hav...
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...
Hello , I am aiming to demonstrate secure storage operation SST using PSA APIs using STM32U585. To verify that TF-M services are operational and Secure/Non-Secure communication works. However I dont find any more stm32cube TFM ready solutions/example...
Hello, I'm looking for some advice on how to progress, beginning from a fairly novice position, with a secure bootloader. I'm beginning a project where at least a secure update process (where the existing application does the update) is desired. Id...
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'm running example 03_ECDH from https://github.com/STMicroelectronics/STSAFE-A120_examples/tree/main/Applications/Projects/03_ECDHI modified the example to use ED25519 / Curve25519. I pasted the public key of some key I generated on my PC into the C...
