Oops hold it on that paywall URL issue.  I responded with a different paper.  All else is still ok, but let me dig a big more on that paper for non-IACR members. On 1/18/21 11:06 AM, Robert Moskowitz wrote: On 1/18/21 9:12 AM, Eric Vyncke (evyncke) wrote: Standard TD ;LR : more work to be

X25519 (and x448) is the only curve remaining in HIP DEX. In checking on this, I see I do need to remove text from 9.3 which is the only remaining reference. Of course there is the valid question of why x448 is still there. Probably should remove it as well. So looking into p384: If you

Thanks for the link. However, this paper appears only to cover X25519. We'd need a comparison of this to P384, etc. in order to assess the relative performance of SIGMA-style protocols with NIST curves with HIP-DEX with X25519 On Mon, Jan 18, 2021 at 8:35 AM Robert Moskowitz wrote: > Ah, found

Two months after the email below, I sending a kind reminder to authors and WG. With the -22, a lot of (if not all ) SEC ADs’ DISCUSS points should have been addressed. As far as I can tell, the other remaining issue was Ekr’s one about why forfeiting FS when some algorithm could do it in a

More fine-tuning. Please look at the diffs. Please note, that I have not been able to find any energy consumption numbers to go along with the cycles for the EdDSA signing and verifying.  I do not believe it is trivial; not from conversations I have had.  Also I am not sure you can simply
