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...
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.
I am using STM32L5, In our project, we want to create one script which will lock the bootloader option and enable RDP to 0xCC to disable JTAG.We are using the SBSFU example as a base and developed our application on it.In script Regration.bat, 0xAA R...

hi St team, thank you for your support.My objective is secure boot for my independent project. i am using stm32L562vet i am able enable trust zone with RDP level =1 and able to disable the trust zone using RDP regression. now i want to implemen...
I am using TFM-SBSFU example provided in STM32L5.Secure Area 1 which is already configured as below.When I am trying to read 0x8012000 from non-secure application, I am getting secure fault. I want to add one Partition 0x807d000 of 4KB into secure a...
I am using the SBSFU example of "NUCLEO-L552ZE-Q" Projects.I have added my application code to the NON-Secure application project.When I see "Region_defs.h", in which nonsecure (NS_TOTAL_RAM_SIZE ) size is 192 KB whereas secure (S_TOTAL_RAM_SIZE)size...
Currently, my program cannot be executed, and it is useless to pull up the boot pin, and STLink cannot be linked. There is a way to reset the chip register boot_lock, TZNE, and RDP? or how to perform full chip erasure?
i am enable trust zone and I make one part as secure world and another part as a non secure world using (SECWM1, SECWM2) but forget to enable Dbank as (Dbank = 1) now I couldn't make any changes in option bytesmy question is1.how can I enable dual b...
