I want to use AES peripheral for encryption in ECB mode (256). I am able to encrypt and decrypt on the same MCU, but if I compare the encryption results, the HW peripheral has a different result than the SW library AES.c or encryption in Python - the...
Hi,I am currently using the M3_CryptoFW_RngHW_2_0_6.lib for MDK-ARM. However, I must adhere to this specific library version, and I now need it for IAR, meaning that the required library is M3_CryptoFW_RngHW_2_0_6.a. How can I obtain this version for...
Here is my attempt at background as I understand it... iROT is a ROM program in the STM32H563. It contains a P256 EC algorithm, and checks some section of FLASH that you define as a program for a signature, then jumps to it. The definition of the pro...
I have STM32U5 MCU and the TrusZone is disabled. Is it possible to have secure boot or not. If yes, please can you explain to me how I can achieve this. Thanks a lot0 Kudos Reply
I have a problem with merge SBSFU .elf file and application .elf.I prepared:SBSFU.elf - addresses in linker script: 0x08000000 - 0x08020000application.elf - 0x08020400 - 0x081FFFFFheader.bin - size: 1024BSo I suppose, that like in SBSFU example heade...
The call to "cmox_rsa_pkcs1v15_encrypt" requires a "Random buffer" and a "Random Length (in Bytes)" as input parameters. It will return error code CMOX_RSA_ERR_WRONG_RANDOM if "Random material too short or not valid for the functionality".I keep gett...
Hi all,we would implement SBSFU (Secure Boot and Secure Firmware Update) on STM32U585.Our goals are:application do not use TrustZone feature (TZ_EN = 0)we want to avoid access to MCU on field (Device protection, for exapmle RDP = 1)question: if on fi...
Hello all.I have a question about how to use KMS_GenerateKeyPair() function. There are no examples in the code, and API description is not really enough for my little brain. Could somebody provide me an example on how it should be used? What kind of ...
Hi,My question is about project structure.To implement SBSFU what is the best or correct approach if I have a project that I would like to flash to a target incorporating SBSFU?Import four project folders (SBSFU, SECoreBin, UserApp and MyProject) int...
Hello .According to the reference manual, the default RDP level is set to level 1. However, after performing a full erase with ST-Link and then writing the hex file, the RDP level was found to be set to 0.I would like to set the RDP level to 1 at the...
