Hello guys, how are you all?I'm currently developing using the X-NUCLE-SAFEA1 board integrated with an STM32WB55. I was executing the pairing example generating a randomic mac and cipher key. I stored successfully this keys into the STSafe, but my pr...
The datasheet on STSAFE-A110 seems to clearly state that the chip provides symmetric encryption services, however the Cube expansion package and middleware in there does not appear to support that. Where can I get the examples of using this feature?
Hello,I am trying to generate the combined elf file with SBSFU and user app. The provided postbuild scripts use the following code to create the file:command=$programmertool" -ms "$elf" "$headerbin" "$sbsfuelfThere is a problem that the combined elf ...
I can not even disable default polynom (in case of STM32L412K8Ux):For STM32G071 it allow me to disable default, but it force on some value (probably default) - it does not allow to enter our own.I would like to set 0x8005 polynom in cubeMX instead of...
I'm trying to configure a secure area (HDP) for a H735. To do so, I am following the steps described in AN5601 HDP secure area for STM32H7B3xx microcontrollers using the examples HDP_Appli and HDP_Boot for the STM32H735G-DK. The application note does...
I am using STM32L562E-DK.I have ported SBSBFU for it. It is working fine. I want to store my custom data into internal flash and read it on bootup time in the bootloader.For testing I am flashing one binary of 16 byte which's content is "Hello World!...

I am trying to build Alexa build in device on X-CUBE-VS4A runs on the 32F769IDISCOVERY board.I have registered this as a new product under my Amazon account and need return URL example (http://stvs4a/grant_me) details Which I can enter under Amazon s...
I am developing some products based on STM32F407/STM32F429. What I am trying to do is to protect my firmware that:simply dump the code from one chip's flash (to hex file) will not work in another chipmoderate reverse engineering should not be that ea...
Hello,I am designing a firmware for an IoT that needs to be able to be updated securely. I decided to use the X-CUBE-SBSFU package. From a crypto point of view, the requirements are that:The firmware update needs to be confidentialThe firmware update...
