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
