I've been trying to set up the AES peripheral so that it's only using the hardware derived key from the SAES peripheral (without setting any clear text key). However, the only method mentioned in the reference manual on using the DHUK is through the ...
We are using STM32H750VBT6 rev V and have encounter boards with mcus that freezes when we try to use the CRYP. So far we have seen that on failing boards the crypto registers are zeroed immediately after initialization but on a functional board ther...
Hello,I'm trying to use the SAES/AES shared key functionality in a Trustzone (TZEN=1, RDP = 0), using the functions provided by the HAL library. The board I use is the B-U585I-IOT02A.The only project example I found is with Trustzone disabled, but it...
Hi,I'm trying to encrypt and decrypt in my device, running on a STM32H753, using AES ECB.I'm initializing crypto like this: hcryp.Instance = CRYP; hcryp.Init.DataType = CRYP_DATATYPE_8B; hcryp.Init.KeySize = CRYP_KEYSIZE_256B; hcryp.Init...
Hi everyone,I'm working in a Medical devices company and we use currently plenty of STM32s (F0,F1,F4, maybe soon H7). Until now, we didn't bother that much the cybersecurity topic for the firmwares but now the norms are forcing us :D.I checked a bit ...
Porting SBSFU 2.6.2 to STM32G0B1CEU6 (512K FLASH and 144K RAM) based on Nucleo-G071RB example.See the history of my previous Solved: SBSFU 2.6.2 firmware swapping issue - STMicroelectronics CommunityAfter I solved the firmware swapping issue, I went ...
I've tried to enable the CRYPT and HASH peripherals by setting bits 5 and 4 in the AHB2ENR register, but all peripheral registers read as zero and writes are ignored as if the clock wasn't enabled or the peripheral was missing. Does this chip have ha...
Hello all, I am using the SBSFU v2.6.2 on STM32H753 - (2 slots based) for a few months now, and am trying to enable the Firmware Rollback feature right now. During this attempt, I had enabled ENABLE_IMAGE_STATE_HANDLING as required in SE, SBSFU and U...
Hello there!I've been trying to make the Lora-FOTA example portable by converting the include paths, resource links, linker path and pre/postbuild files to be "project related paths" instead of absolute paths.Everything worked out very well with kms_...
Hello, I am using the STM32 Cryptolib. I need to get the modulus and exponent of RSA public key from a .pub or .pem files. After decoded from base64 I need to decode the DER format (in ASN.1 format). Has anyone any suggestion of which libray may I us...
