Resolved! stm32u5 aes cbc 192 bits
Hello,I need to implement AES-CBC 192 bits on micro STM32U5 serie, but hardware only supports 128 or 256 bits If i use XCUBE-SAFEA1, ST_Cryptolib is not available for U5 serie.How can i fix this issue?

Resolved! SBSFU with encrypted CBC in KMS?
Hello,We are developing a product based on a STM32WB5MMG. We have configured the SBSFU with OTA (Asymmetric with AES encryption scheme). Everything is working great and I have only one question that came to my mind during the last commit...The CBC ke...
H573 TrustZone Callable Secure Code
Is it possible to call Secure (S) application code from Non-Secure (NS) application code with TrustZone on STM32H573? I have not seen any examples of this from ST, so I want to know if it is possible or if there is some fundamental reason why not.Th...

Hi all, first time working with stm32.So far I've managed to make things work, I've even workarround this issue (*), but I can't seem to understand why this is happening in the first place.STM32F429, STMCubeIDE, ST-LINK/V2This is my situation:Executi...
Continuous reset loop with SBSFU on STM32L4R9. Reset always happens right at the moment the secure engine is called.
When the Secure Engine Call (inside SE_Init() function) is called in this line:e_ret_status = (*SE_CallGatePtr)(SE_INIT_ID, peSE_Status, primask_bit, uSystemCoreClock);(which is between a SE_EnterSecureMode and SE_ExitSecureMode). The MCU resets at t...
Resolved! SFI
Am searching for SFI documentation without HSM to demonstrate to a Device certificate authority. Can you please share UserManual or ApplicationNote for STM32H573I-DK.BestRegards,P.Hitesh
What is the MIPS figure for X-CUBE-CRYPTOLIB HMAC SHA-256 Implementation for STM32F429 (Cortex M4)?
Hi, I'm looking into introducing HMAC SHA-256 on my STM32F429 based project as part of a requirements change. As a first go/no go, I'll need to know what is the worst case required MIPS figure and memory foot print (SRAM/FLASH) for running the algori...
NUCLEO-H745ZI-Q SBSFU adaptation cannot boot CM4 image.
Hello, I am trying to adapt the H753xx SBSFU implementation to the H745xx dual core board.I have so far configured a second slot by creating a second MPU region of 1KB to protect the header of the second slot, as well as changing the security checks ...
Access to UID_BASE from non secure application on Stm32U585 under SBSFU cube example
