Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Hi, I just went over the X-Cube-SBSFU material and tried to compile the example projects to get an overall picture of this function.The MCU I used is STM32F730I8 and I am using the STM32F7308-DISCO board.As only 64kB flash is available in STM32F730 s...
I am trying to use the hardware peripheral on the STM32F030 to calculate a 16-bit CRC for a modbus RTU application. But I don't know how to do it.
Dear all. How secure is STM32 MCUs to prevent hackers from dumping the firmware from the flash memory? I've searched on the internet and on Taobao (like ebay) China and I found there are plenty of companies that claim they can crack and dump the fla...
For example, Im looking at the STM32L073RZT6 This documentation from ST states there is "128‑bit AES hardware encryption".https://www.st.com/content/ccc/resource/sales_and_marketing/promotional_material/brochure/6c/48/c0/f1/bb/35/4a/b4/brstm32ulp.pdf...
Is there a list of STM32 based Mbed supported MCUs that have hardware encryption?I'm looking for the cheapest options.Many thanks
The reference manual gives a brief description but how do you actually implement it?I'm using an STM32F437 which includes a cryptographic accelerator so I'm not looking to use the Cryptographic Library.Any documentation, tutorial, example code or any...
Hi,In my company we are currenlty looking at integrate the crypto lib.I have created a small STM32 IDE project to test the crypto lib provided by ST. I am using the Nucleo STM32413. The whole project compiles and I can succesfully call AccHw_AES_CFB_...
Hello,When the RDP level 1 protection option bytes is set and the boot adress is set in the user flash memory, what are the debugger protections ? Which parts of the microcontroller still remain available via the JTAG debug port or the SWD debug po...
According to following white paper, some STM32 MCUs has security issues.https://www.usenix.org/system/files/conference/woot17/woot17-paper-obermaier.pdfThe question is Which STM32 components are affected?We are considering to use STM32H750vb and STM3...
Hi all,I am generating a CRC using the hardware CRC module in my STM32L0 of which I fetch only the bottom byte.I want corresponding C code to generate the same result as the hardware calculator, I have tried many different settings and Polynomials, b...
