STM32 MCUs Security

For a new line of products, we are considering STM32F750 but it lacks on-the-fly decryption support. Is there a new line of microcontrollers planned that matches the spec of STM32F750 but includes support for on-the-fly decryption

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...

SBSFU User Application integration

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...

Is it possible to read data from user flash of STM32H743ZI in RDP level 1 using race condition access through debug interface?

I want to know how much secured the user flash of STM32H743ZI in RDP level 1 from hackers.

In STM32L4 for CRC, what does it mean "Even polynomials are not supported"

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...

include Crypto Library in STM32CubeIDE

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...

HAL Problems with SPI(slave) + DMA + CRC(hardware) in stm32f373

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...

How to add STM32 cryptographic library in a project using kiel IDE??

When using X-cube-sbsfu, why is swap area size constrained to be at least equal to the size of the largest flash sector? Is there a way to modify SBSFU to work with a smaller swap area?

On STM32F746, largest sector is 256K and total flash size is 1M. This means that 1/4th of our flash is lost to the swap area. As a result, we do not have enough flash memory left to implement the dual image variant. We are now trying to optimize the ...
