Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
How can it be, that the CMOX library implements `append` functions for hashes (like cmox_hash_append) but the equivalent for verification or signing of ECC algorithms does not exist?How should we check the signature of a 10 MB update package on a dev...
Hi, I am working on NUCLEO-H533RE board. I am checking all the configurations before start of my work. As attached below, The datasheets says that PKA is supported when i opened .ioc file, It is visible as greyout. I am not able to activate it. Even ...
Hi, I would like to work with the security features of STM32H533RE microcontroller. For that,1.Do I need to enable anything or install any libraries files in order to work with it.2. If there is any example projects available?3. The path for Installa...
Hello,I would like to replace ECC public key in SE_Key_region_ROM region from my application in runtime. My device has no protection enabled (RDP, PCROP, WRP). I am able to read and write in the region via CubeProgrammer.I dumped the 256 bytes of SE_...
Hello TeamI'm facing below error in STM32CubeIDE while compiling the source code in "Release" mode:"Unable to Generate Command Line in STM32CubeIDE" And it's getting stuck at below point:# Each subdirectory must supply rules for building sources it c...
Hello,We want to use the STM Crypto Library " X-CUBE-CRYPTOLIB" for a project at our company. Since we will only be using a portion of it, the question arises whether it is possible to customize the static ".a" file ourselves (to make it smaller) or ...
Hi All,Does the SBSFU reserve all of the DTCM in an H7 (stored state information, etc., expected to be stable across Core resets) such that the application shouldn't touch any of it after beginning execution? The "Protected RAM ..." note in AN5056 F...
Hello everyone,I would like to implement a project using TrustZone on the STM32 L562 Discovery board. To get started, I based my work on the STM32Cube_FW_U5_V1.4.0\Projects\NUCLEO-U575ZI-Q\Examples\FLASH\FLASH_EraseProgram_TrustZone\ example, which i...
