My err - rubbish wording as I was thinking primes and talking curves.
Still, while I'm punching here a wee bit above my weight - I should read the 186-4 again - there are some tests to verify the strength of the prime. Is it enough for a similar classification? - I don't know...
- tptacek 10y agoThe prime field is part of the definition of the curve. Everyone interoperating on that curve shares it. It may have been generated weirdly --- the Curve25519 prime sure was! --- but all that tells you is what curve they're using. It's true that the particular curves a system supports could be a kind of fingerprint, but that's a banal observation, equally true of the ciphers they support, or the compression algorithms.
