Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
I have implemented sbsfu on my board. It is running. If I download a new firmware out of my user-app the new firmware is loaded, the flash is swaped and the new firmware starts up.If I reset the board, the bootloader says - Installation not validated...
I'm using STM32L562VET6, please tell me where I can find "X-CUBE-CRYPTOLIB" support Cortex-M33.Thanks,QiZhang
Hi, Trying to turn on RDP just before I get a product out to market. Can unlock and erase Option RDP bits to 0xFFFF but cannot seem to write the option bit to set RDP byte to 0x00FF. This leaves the devices bricked on the next reboot. Can't era...
Hello everybody,we're currently discussing product tampering and intellectual property (IP-) protection for a new product.I read a lot about SBSFU, the STSAFE processors and KMS memory in some STM32 µCs, but some things I may have not 100% understood...
Hi,I am migrating some code from an STM32F745 to an STM32H743.I came into some trouble while using the crypto library and the hardware CRC at the same time.The STM32H743 crypto library resets the CRC DR register every time AES_CBC_Decrypt_Append is c...
Hi all, Is there any method available for program RDP 0xBB to RDP 0xAA using CLI only through the uart or spi using USB ( without SWD or JTAG)Thanks
I went through the MOOC part 6 and I thought of creating a new project for Nucleo -L476RG (from the scratch), I Created a new code using CubeMX (Use same pins ands USART) and followed the same steps as video 2,4 as describes. but once I use FLASH_SBS...
Currently working on a Bitcoin hardware wallet on the STM32F7 Discovery platform. I wanted to use the cryptographic library to secure information stored in the EEPROM as well as perform hashing functions. VFP is not supported in libSTM32Cryptographic...
Hi all, I am porting the SBSFU to the custom STM board which is running in the Stm32L476JGYx. Normally user button is connected to the PC13 in the Nucleo board and in my custom PCB I made the user button for the Boot0 (PD7) I use this only for the bo...
I'm trying to use the STM32F439ZI HASH accelerator with the following code:#define INPUT_SIZE 16 static uint8_t hash_test_buffer[224] = {0}; static uint8_t hash_test_output[224]; HASH_Start_DMA(&hhash, hash_test_buffer, INPUT_SIZE, HASH_ALGOSEL...
