Hi, I am working on the STM32H533RE microcontroller and implementing AES-CCM encryption using a NIST test vector for validation. While the encrypted output matches the expected result, the authentication tag generated is incorrect. I have shared the ...
Hello! I would have an app that is divided between a secure part and a non secure part. The memory definition is as following in the secure linker script: /* Memories definition */ MEMORY { RAM (xrw) : ORIGIN = 0x30000000, LENGTH = 320K FLASH (rx) : ...
Greetings,I want to implement encryption in STM32F205RG. I came to know that there is no Hardware support, so is there any STM32 crypto library for STM32F205RG ? I want to implement AES encryption and decryption function. Thanks for support.
I am still very new to embedded programming. I am trying to walk through the SBSFU example application for the B-U585I-IOT02A from STM32CubeU5. The board I am using is STM32U5A9J-DK. I tailored some of the build settings in STM32CubeIDE for STM32U5A9...
For context , i was trying to testout OMEiRoT and DA ,i successfully managed to lock , and regress using the password method and i tried to replicate the STiRot method shown in the STiRot handson video to try the OMEiRoT example project in the nucle...
Hi,I'm using an STM32H563VG (1MB Flash version) on a custom board. I have a STLINK-V3MINIE connected and I'm using STM32CubeProgrammer.When I'm doing a full chip erase, the content of the flash memory is not altered, everything is still there when I ...
I am testing this with a set of STM32F573 boards, the example taken straight from CubeMX example selector for the STM32H573I-DK board without any changes. I am running it until after the call to HAL_CRYPEx_WrapKey() and before the call to HAL_CRYPEx_...
Good day!I have custom board with cpu stm32l562. I am prepared all data and global license. CPU prepared by script file from package STM32CubeExpansion_SFI_v1.5.0 L5.This operation is OK.But after if start programm by Cube Programmer ( v 2.19 ) - i h...
STM32H730, an invalid tag is generated for payloads that are not a multiple of 4, as described in Re: STM32U545 AES GCM Tag mismatch - STMicroelectronics Community.AES-CCM: no issues, everything works.AES-GCM:The HAL already handles required padding ...
In the past I've used F401 and the following code works flawlesslyHAL_FLASH_Unlock(); HAL_ICACHE_Disable(); uint64_t myWord = 0x00000001; HAL_FLASH_Program(FLASH_TYPEPROGRAM_DOUBLEWORD, 0x080C0000, myWord); HAL_GPIO_WritePin(LD2_GPIO_Port, LD2_Pin, G...
