I try to understand in details the way the Hash peripheral works on the STM32L552. I need to make the HASH SHA-256 with 224 blocks of 512 bits. The Hash works perfectly until the block 223. Then I enter 16 values in the FIFO (in my code below I have ...
Hello.I'm working with STM32H573.I have a question related with the use of STSAFE-A110 for TLS. I have to authenticate also the client.I've succeded stablishing TLS mutual authentication with HTTPS server and TCP server (different applications, not ...
I am using mbedtls module to verify the signature of firmware using RSA and its giving MBEDTLS_ERR_PK_INVALID_PUBKEY after parsing the public key. I am using OpenSSL for generating public and private keys the public key is generated using openssl gen...
Hi, I am using ADC1 on stm32H563ZI nucleo board with trustzone enabled, I am not getting proper adc values (getting adc count of 822). When trust zone is disabled I am getting proper value of around 4095 with input of 3.3Volt .I am attaching the proj...
Using STM32TRUSTEE-SM framework, the non-secure application is built by the project.py script which in turn callsSTM32TrustedPackageCreator_CLI.exe -pb SM_Code_Image_bin.xmlto generate the application .bin file in MCUboot format.The xml file has <Par...
I’m using STM32WL5MOCH6STR and want to add STSAFE-A110 for security in a LoRaWAN application.I want to know:How to use STSAFE-A110 for authentication, key storage, encryption and secure boot & secure firmware update.Which software packages are needed...
Hello STM32 Community,I’ve successfully built a Zephyr RTOS blinky application for the NUCLEO-H533RE board. Flashing the zephyr.hex using west flash or STM32CubeProgrammer works perfectly — the LED blinks and the serial terminal prints the expected s...
Hi,I come to you about the key provisioning process for the iROT in the STM32H5.Using TrustedPackageCreator, the keys provided in the file STiROT_Config.xml for the Secure Boot (field <Authentication key>) are both the private and public keys of the ...
Hello,I'm using STM32F439 with LWIP, SNMPv3, and mbedTLS, without FreeRTOS. I've encountered a performance issue when using the hardware acceleration for AES and SHA1 provided by ST (aes_alt.c, sha1_alt.c).Specifically, when decoding SNMPv3 messages,...
Hi everyone,We’re developing an IoT node for agricultural applications and plan to make it compliant with certification requirements (CE, CRA, RED).We’re using the X-CUBE-AZURE package as our starting point and want to use TF-M (Trusted Firmware-M) f...
