Hi, I just accidentally modified the PRODUCT_STATE to provisioning and not able to recover.So, I tried to do the OBKey Provisioning and use DA to regression back to Open State.I've created my OBKey:However, provisioning always failed.Is there any oth...
I am worried about the data that i send through the STM32WL55JC if any outsider with the same board and using the same frequency in receiver mode ,can also get the data that i am sending through the transmitter using same frequency ,How do i secure m...
Hi Good day, Trying to understand the CRYPTO module for MAC generation, particularly AES CBS MAC. Which algorithm mode i have to choose?, found AES CBC not AES CBC MAC.
Hi,I´m trying to implement a simple ECDH test by implementing the functions from the Cryptographic Library V4.2.0.There are two persons A and B generating a pair of private and public keys. The keys are generated by the cmox_ecdsa_keyGen(...) functio...
Hi, how to do signature verification in stm32u575 with RSA-2048?
Hello everyone,i am trying to enable the secure user memory on the stm32h743 using the x-cube-sbsfu project and have the following problem:After activating the security bit, the value of the OPTSR_PRG flash register is not changing, so the security b...
Hello. I'm trying to obtain CRC value from CRC peripheral. It's supposed to give me 8 bit number. Instead it gives me 32 bit number. What am I doing wrong? Below is the code and program outputs. /* USER CODE BEGIN Header */ /** ********************...
HiWhen I was returning from RDP level 1 to 0 the stm32cube programmer program crashed and now every time I try to access the microcontroller several different cases happen:1- Connect and instantly lose the connection giving the next error: Error: Dat...
Hello,I am using the X-CUBE-SBSFU package with the KMS to perform firmware update on my ST MCU.To verify the authenticity of the firmware I use ECDSA. However, I don't understand why I only need to provide a private key but not the public key. If I u...
Hi,I'm using STM32CubeExpansion_Crypto_V4.0.1 library for verifying a signed firmware file on STM32F7 controller. The key-pair has been generated using openssl command-line. The firmware has been signed using the private key (PEM). The signature has ...
