STM32F4 random number generation validation

Hello all,I am working on a cryptography project based on STM32F407VGT micro controller, in which I need to generate random data using inbuilt RNG peripheral. I dump this random data to my Ubuntu 16.04 host machine using USB in CDC mode and using l...

STM32l432KC can not work after changing RDP level from 1 to 0 although chip was re-flashed new code successfully.

Dear everybody,I have a STM32L432KC chip.Firstly, I flash code and set RDP level 1 and PCROP_RDP flag to 1. => everything works fine.Then, i want to reflash code, so I changed RDP level 0 to 1 -> Chip mass erase and flash code again. But chip seems n...

Warnings while using CRC drverfiles

Hello All,We have designed a custom board with STM32F777IITx MCU on it, where i am using ST Micro's CubeMX with Atollic True Studio for developing the code.Now I am also using a USB host peripheral and reading data from USB device now this data read ...

Protect firmware updates.

Hi all!,In the case of a commercial device, who need periodic firmaware updates, is there a way to protect those updates in order to avoid for being copied and cloned?Someone can point me to a read about it?

Does anybody know if it is possible to use the ST-Cryptolib (FW lib) functions for mbedtls_ecdh_gen_public and mbedtls_ecdh_compute_shared?

Import Elliptic Curve Keys From .pem Files

Hi, I am coding on the NUCLEO H753ZI board with the pack for embedded cryptography (x-cube-cryptolib-3.1.2). While this folder provides example with hardcoded keys, it does not provide an example with keys imported from a file. Typically, I would lik...

STM32CryptographicV3.1.1_STM32H7 and RNG

Hello togetherI use the following library to create random numbers:- LibraryThe sample project runs on my NUCLEO-144 H743ZI. The problem is that the same byte array (RandomString) is generated at every time. *****************************************...
