How do you know how big the preallocated static buffer should be when calling cmox_rsa_construct?Does this depend on the RSA key size that will be used?Does this depend on the Modular Exponentiation function that is selected (LOWMEM, MIDMEM, HIGHMEM)...
Hi,Im trying to encryp using AES 128 CTR but i dont get the same result that online calculators.Im using this online calculator: https://cryptii.com/pipes/aes-encryptionMy code is the next:uint8_t IVKey[] = {0xDD, 0xF9, 0x11, 0xA6, 0xDD, 0xF9, 0x11, ...
I'm having issues with a project based on an STM32WB5MM where some devices fail to operate BLE (like advertising, for example). The project integrates SBSFU and BLE_ota. I'm reviewing the linker files and I see differences in the management of the BL...
HI,we are interested in a guide to a clear workflow of integrating CubeMX-generated code for U5 into TFM-based application.In particular:1. We have trustzone-enabled CubeMX-generated app with Azure RTOS and TouchGFX. The IDE and compiler are IAR. We...
Hi,In our application, we want to authenticate our IoT devices in Azure IoT Hub using X509 certificates with the help of STSAFE-A110. The application is written in Zephyr RTOS and is using the MbedTLS library for the TLS part. Using the in-tree Zephy...
Hi Team,I am working on project in which we are implementing Secure software upgrade feature using SBSFU. locally I am building SBSFU package, but our project follows different process. To meet that I need to build SBSFU package in TeamCity.could any...

Hi,How to authenticate a device connected to STM 32 using USB Peripheral the STM 32 is integrated with STSAFE IC , How to use peripheral Authentication Example for this in the software package
I am integrating SBSFU with the STM32L496ZG microcontroller and have created a new project. I attempted to generate the SFB file using a customized post-build script from the L476 Simple App example. Although I modified the script paths for my projec...
I'd like to open a small discussion about what would be the best usage of STSAFE-A110 to enhance the hardware-level security of our IoT device. To be more specific, in our application we want to use the STSAFE-A110 to store the customized device priv...
