Hello. I am trying to encrypt/decrypt data in secure area of stm32h563 (Trustzone application), using code from one of the examples (using cmox_cipher_encrypt function). Running the function in non-secure area, everything works fine. Trying to run t...
Hello everyone.I'm novice in cryptografic,I'm developing a project with STM32H7.I have a file on uSD and I can read it using FatFs.I have to crypto this file using CRYP_AES_GCM.I setup IOC in this wayThe IOC build this file for meMy file has 98MByte ...
Hello everyone!I’ve been struggling for a while with TrustZone projects on the NUCLEO-U575ZI-Q. I’ve tried both the STM32CubeU5 example projects (Templates/TrustZoneEnabled/ and Examples/GPIO/GPIO_IOToggle_TrustZone/) and my own CubeMX-generated proj...
I'm recently working on benchmarking a various implementations and configurations of cryptographic algorithms such AES-GCM on STM32. Two of these tested function are the following :void test_aes_hardware(void) { uint32_t plaintext[DATA_SIZE/4]; ...
I am currently working on an STM32 TrustZone project and trying to implement the following flow:NonSecure world running↓Calls Secure_add()↓Secure world executes↓Returns value 8↓UART prints the result in NonSecure worldHowever, I am facing an issue wh...
Hello STM32 Community,I am stuck in a critical situation with my STM32H533RE custom board and need help recovering it. I have exhausted all methods I know.- Hardware Setup: - MCU: STM32H533RE (custom PCB, not Nucleo) - ST-LINK: External ST-LINK...
According to the manual, I cannot determine under what conditions the INFIFO will assert the interrupt. The interrupt-related registers only provide two status flags: empty and not full. The IN FIFO has a depth of 8 words (8×32 bits). However, the la...
Hello,I have managed to lock a couple of Nucleo H503 boards and, while they are not very expensive, I would like to try and understand the problem so we can avoid it on production boards.Although I have been experimenting with setting security option...
Hello,I am interested in the optional decryption sequence part of secure boot on STM32N6 mcu. As described in UM3234 (How to proceed with boot ROM on STM32N6 MCUs) a key derivation function is used to produce an encryption key. However I am not sure ...
Hi,I'm using two STM32WLE5 LoRa as TX and RX and added AES-ECB Encryption with Hardware Accelerator in the TX side and receive and decrypt it in RX side with the same Key. Now I want to change the TX module and want to implement same logic of AES Enc...
