Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Normally the bootloader is the first thing to program in the MCU by the manufacturer,. Bootloader contains a way how to update the firmware of the device from the firmware file (encrypted), which is openly passed to the customer. Hence the bootloader...
I tried to do an experiment with PC-ROP protection in Cubeprogrammer, but an exception occurred when I disabled protection.My Memory Data seems to be protected all the time, the value is always 0, and there is no way to Erase the entire Chip normally...
Hi everyone,currently, I'm struggling to make interrupt working with SBSFU (STM32WB55).If I run the program without SBSFU, interrupt event working properly.but when I compiled it along with SBSFU, the interrupt not working.I see on another post that ...
Hello everyone! I encrypt the data with the AES-256 ECB algorithm using the X-Cube-Cryptolib library, while the library itself can decrypt the data correctly, and third-party libraries decrypt it incorrectly. I use 32 random bytes as the key.I tried ...
Hi All,Currently I used SBFU solution to develop project , I had checked the AN2262 that descript SBSFU support below picture.1.My question is how to enhance below encryption strength or any application I could reference, does it need modify SE engi...
Hi!Can someone explain to me why this code:// Is FLASH_CR register locked for writing? if (FLASH->CR & FLASH_CR_LOCK) { // Unlocking FLASH_CR register FLASH->KEYR = KEY1; FLASH->KEYR = KEY2; } // Unlocking FLASH option register if (FLASH->CR & F...
I wont to test the L432KC example on a NUCLEO-L432KC board"\SBSFU\STM32CubeExpansion_SBSFU_V2.6.0\Projects\NUCLEO-L432KC\Applications\1_Image"I have created correctly a new workspace and imported the necessary projects. All compiles fine and I get "S...
Hi,I am trying to run the CRC calculation with the STM32G031 but the results do not match. The result of the CRC16_CCITT_FALSE should be 0x29B1 according to http://www.sunshine2k.de/coding/javascript/crc/crc_js.html but I get 0x277F.You can find my i...
I'm attempting to use the serial bootloader to load a secure firmware image to an STM32L5 using STM32CubeProgrammer. I can successfully connect to the board in bootloader mode and perform a full-chip erase, but attempting to download the image (eithe...
