Hi
I found this email on ARM MBED support forum.
Could you help to resolve our issue?
On the PSoC6 device we are using mbedtls_rsa_gen_key function with a good hardware TRNG passed FIPS 140-2 verification.
This function verifies generated random pair and requests new pair if they don’t follow FIPS 186-4 criteria.
The number of verification loops is between 1 and 6 in worst case.
Is it expected behavior?
The arithmetic of one loop takes a lots of time.
How can we improve the random number to have always pass FIPS 186-4 in a one loop?
Thanks
Nazar
