I'm using cmox_ecdh for generating shared key for STM32G431KBT6. I tried using single call API from AES_CBC_EncryptDecrypt example and provided Computed_Secret instead of Key in cmox_cipher_encrypt function but I get bad parameters error. I dWith the...
Is it possible to compute the ECDH shared secret (pubkey * privkey) by using HAL_PKA_ECCMul, replacing the generator X and Y with the public key X and Y and specifying the private key as the scalar value?Thank you.
Hi ST Team,I am using STM32U575 MCU. I want to create signed binary. I want to upload signed firmware in MCU and also update only new signed firmware via Native bootloader and want to restrict unknown firmware updates.How can I create signed firmware...
Hello ST Community,There was a thread by Aurelien about this topic, but I did not understand the answer. So let me rephrase the question with my own words.I have a STM32U5 based device with high security settings (TZEN=1, RDP=2). Is there any other m...
Hi all,can anyone pls suggest any leads to understand more on the anti tamper, i want to understand more on the internal tamper, external tamper , active and passive tamper in details, if any leads would be a great help,
Greetings, supportTeamEnjoy your day. I'm working on the STM32U585 Series' firmware upgrade procedure. I have a development kit (B-U585I-IOT02A) for POC purposes. I'm using TFM-boot, TFM-Loader, and TFM-Application for firmware upgrades. I activated ...
We currently utilize the STM32H7B0xB microcontroller, which offers 1.4 MBytes of RAM and 128KBytes of flash memory. While exploring the SBSFU examples found examples for running from external flash directly, I could not locate one that specifically d...

Hello,I need a quick confirmation. Assuming I have correctly provisioned OEM1KEY and OEM2KEY and I don't use OTP memory, I will always be able to revert my STM32U585 chip from RDP level 2 to blank state (RDP level 0, erased Flash, TrustZone disabled)...
Hello,I am working on integrating SBSFU with the STM32F4 controller. The target controller is F429.I am trying to build an example project. It is a single image slot project which is developed for STM32F413H. I build the SE_Corebin project first and ...
