Hello, Is it possible to custom the header of a firmware for SBSFU ? I want to add 2 variables but it's not working. I have authentification failure. But I don't change the size and position in the structure because I used the "reserved" bytes. (the...
I'm trying to compute the ECDH shared secret by multiplying local private key and other party public key using HAL_PKA_ECCMul. For some reason it is not working. I'm using curve secp256r1. But I'm able to use HAL_PKA_ECCMul to generate public key by ...
Hello supportTeam,Have a nice day.I am working on B-U585I-IOT02A development kit and i tried merge our application with SBSFU_Boot and SBSFU_LoaderI've included the steps I take to integrate my own application below.1. Create Project Name: Applicatio...
Hi,I am trying to modify the SBSFU example provided with STM32CubeU5 to run my own application. I generated the code with STM32CubeMX for IAR by enabling TrustZone and leaving the default values set by STM32CubeMX. I wrote my code, deleted all the fi...
Hi, I’m working on a STM32L552ZEQ.My goal is to generate a pair of RSA keys of 2048 bits using the Trust Zone.Before start using the Trust Zone, I wrote the code to generate the RSA key pair (of 2048 bits) without the Trust Zone, and the average time...
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...
