Hello,I am using the Nucleo-STM32F411RE development board and require support for cryptographic functions, particularly ECC NIST P-256, MAC, etc, for my development use cases.To achieve this, I downloaded the X-CUBE-CRYPTOLIB v4.3.0 package as it was...
Hello, I am trying to adapt the H753xx SBSFU implementation to the H745xx dual core board.I have so far configured a second slot by creating a second MPU region of 1KB to protect the header of the second slot, as well as changing the security checks ...
Hi,I am struggling to get `HAL_PKA_ECCCompleteAddition` implemented correctly, that is, if I'm comparing the projective coordinates with a reference implementation, the results don't match. Same goes for converting the projective coordinates back to ...
Hi,I try to use PKA for some ECDSA computation. For this purpose I needed to use PKA block. However, in SR register, I never get INITOK bit set. I am working with TrustZone enabled. So, STiRoT is executed before my program.After investigation, I've s...
