Hi everyone, I develop a asimmetric public/private key crypto scheme and then with simmetric derived ley establish a comms with HOST REMOTE <-> [LOCAL HOST/STSAFE]. I generate with ephimeral slot with:ret_code = (int32_t)StSafeA_GenerateKeyPair(hand...
Hello,Can we run STM32CubeU5 TFM Application (UM2581) on U575 since it has not crypto hw like U585?Thank you in advance!Best Regards!
I'm aiming to use the OEMiRoT sample project as a concept for secure updating of a large single-slot application in STM32U083 (need application size at least 160kB for migration from STM32L071). For that I need to give the bootloader a driver for ext...
Hi,I'm trying to get started with the SBSFU (2.6.2) on my custom board running an STM32L4A6. I've got a large external SDMMC flash chip (4GB) connected to the STM32 that I use for user application purposes. I'd like to allocate a small section of t...
Hello.I'm having trouble transfer the UserApp to SBSFU. Here's the description of the issue. Any help is appreciated!I prepared the NUCLEO-H753ZI board by disabling all the security and fully erase the board (by setting RDP level 1->0 ).I'm using the...
It seems perfectly possible, under Level 2, to have a "boot block" which accepts a firmware block (say via USB MSC or via HTTP), encrypted with a key stored in the boot block, and you have a product whose firmware can be upgraded but can't be extract...
We are doing updates on a project which uses STM32H747 and ST cryptographic library (CMOX) / X-CUBE-CRYPTOLIB. It encrypts and decrypts data using these two functions:cmox_cipher_encrypt(CMOX_AES_CBC_ENC_ALGO, ....cmox_cipher_decrypt(CMOX_AES_CBC_DEC...
We are using the STM32H563IIK6 in our Device.I want to Enabled CRP protection. We are thinking use Level1only. Please can you share any test code.
Hi, I've decided to create a new post based on the similar one (https://community.st.com/t5/stm32-mcus-security/solved-stm32u5-tfm-example-b-u585i-iot02a-memory-mapped-psram/td-p/108722) which has been solved but doesn't work for me.The problem is as...
HiI am using the SBSFU application on the stm32u585 board and I am trying to use the crypto library as explained in the CRYP_SAES_ECB_CBC example but the error_handler is triggered when the MX_SAES_AES_Init is initialized.Any help?
