Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Posted on January 08, 2018 at 10:21 Am I correct that readout protection has a major issue and is not working at all? Are all STM32s affected? Any comments on this from ST? See here: https://www.aisec.fraunhofer.de/en/FirmwareProtection.html ...
Hello,I am trying to decrypt some data on the L5. The data below can be fed directly into a python crypto library and get a valid result. I am trying to understand the 32-bit alignment requirements of the L5 as well as any possible byte swapping ne...
We need a powerful M7 core running at high speed + GPU support for TouchGFX. It seems that STM32F750 is a perfect match, apart from the fact that it is missing support for on-the-fly decryption (OTFD). As we would like to use external flash memory an...
HiI'm working on a ST STM32G474RE with the 2 Images and have a application with STM32CubeMX.I was reading the AN5056 but don't understand how I can build my application bin file to download with the Y-modem protocol. Or do I need to modify and add al...
I want to know how much secured the user flash of STM32H743ZI in RDP level 1 from hackers.
In the Reference Manual for the STM32L41xxx/42xxx/43xxx/44xxx/45xxx/46xxx MCUs for the CRC Unit, it casually mentions "Even polynomials are not supported." But what does this exactly mean? Does it mean polynomials which have even parity are not suppo...
hello,This is an old thread but I hope to get an answer here.I'm using NUCLEO-L496ZG-P, and I have data to decrypt (AES128 CBC).I'm using the STM32CubeIDE to compile.I'm trying to use the Cryptolib but didnt get how to do so. I did download "en.x-cu...
I'm using a STM32F373 microcontroller as SPI slave and can't make it work properly using CubeMX and HAL functions.Master side is OK, confirmed in scope that byte string and calculated CRC for Tx are as expected.Slave side is programmed to transfer vi...
Hi, I’m trying to use the cryptographic library on a board based on STM32L152CBT6-A to encrypt data to be sent. I tried to replace the files inside the “Driver�? folder but it did not work. Does anyone know how to use the library and import it correc...
HiI'm trying to get run the X-CUBE-SBSFU application. I'm working with IAR Embedded workbench. Like in the manual, I built all applications in the following order:2_Images_SECoreBin2_Images_SBSFU2_Images_UserAppI'm working on a Nucleo-G474RE Board. I...
