Hi experts,I need to implement the storage of a security key (upgradable) on STM32H7A3. After reading the example code of KMS under project B-L475E-IOT01A in x-cube-sbsfu, and a few posts in the forum (KSM support on STMH7 and 2-images-kms-port-to-s...
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...
