STM32 MCUs Security

is the Asymmetric Cryptography supports ECC NIST256p keys only ..?? Because i tried to generate ECC private key with help of "secp256k1" and got compilation error as NOT SUPPORTED,

Self Generation script is like this :def generate():       return ECDSA256P1(SigningKey.generate(curve=NIST256p))KEY EXTRACTIONkey = SigningKey.from_pem(pem)       if key.curve.name == 'NIST256p':           return ECDSA256P1(key)       else:         ...

How to port "SPI_FullDuplex_ComDMA_Slave" to "TFM_SBSFU_Boot" on STM32U585

Hi,I want to port "SPI_FullDuplex_ComDMA_Slave" to "TFM_SBSFU_Boot".My MCU is STM32U585.I can port "SPI_FullDuplex_ComDMA_Slave" to "TFM_Appli NonSecure" success, but fail to port it to "TFM_SBSFU_Boot".Do you have any suggestion for it?Please advi...

Include paths?

Hello guys,I'm trying to use the sample project given in the MOOC, and I'm getting compilation errors. The below is the error message.../STM32_Cryptographic/legacy_v3/src/hash/legacy_v3_sha1.c:20:10: fatal error: hash/legacy_v3_sha1.h: No such file o...

Is there a way to use the CLI to set the security read back in the option bits and also execute the start command?

I would like to set the security fuse but also have the application start running. I can set the read protection but after that I can no longer communicate with the unit. Likewise I can start the application using the start command -s but after that ...

stm32l476vcx controller how can internal flash write and read and calculate crc

Solved: STM32H745 CRC->POL Register wrong address in STM32H745_CM4_Peripherals.xml

In the STM32H745_CM4_Peripherals.xml is an 0x10 address offset... correct is 0x14.That is the reason, that I don't see by debugging the value I wrote to this register.

Recommended CPU Frequency for SBSFU ??

SBSFU involved signing verification and encryption/decryption related activities.Also crypto processing is required to implement SBSFU solutions.So, what is the recommended CPU Clock frequency to implement SBSFU solutions ??

Chip Vulnerabilities and STM32 Hacking

Hi - I am new to hardware security researching, so I thought start with a simple STM32 MCU to improve my skills.I can develop simple applications and upload it to flash, everything is ok so far. But I wonder how can I hack the device I developed. For...
