Right. I understood what you meant (I think!). But injecting yet another legal term into this discussion is not a good idea. It's also not a good idea for another reason: it sounds condescending if you know what the legal term means. thanks, Rob On Sun, Dec 15, 2024 at 1:33 PM Eric Rescorla wro

Yes, I'm aware of the legal definition of "attractive nuisance", and I'm using it in a metaphorical sense, which I think is appropriate here. -Ekr On Sun, Dec 15, 2024 at 1:21 PM Rob Sayre wrote: > On Sun, Dec 15, 2024 at 12:22 PM Eric Rescorla wrote: > >> Moreover, as the >> discussion so f

All other guidance about TLS configuration has been in UTA unless it's been deprecating weak algorithms. Most recently the TLS WG wanted the "1.2 is frozen" draft split into two parts, and the other part given to UTA. >> I would express the guidance this way: Use a hybrid that combines PQ >> an

If that draft is useful, it probably belongs in the UTA working group, not TLS. I would express the guidance this way: Use a hybrid that combines PQ and “classic” algorithms, so that if one is broken you’re still safe. If you are required to use only PQ, so be it. __

Perhaps useful: I’m a customer of cryptography but not a cryptographer. I have learned a tremendous amount about the open issues and state of play by reading this discourse. Someone could blog it, and that kind of blog tends to get on YComb and be widely read. But I think it would be of great hel

I don't think it's a good use of the WG's time to put out this kind of guidance statement. Rather, we should simply adopt some subset of the proposed drafts. The Recommended column in the code point registry serves as the TLS WG's recommendation. -Ekr On Sun, Dec 15, 2024 at 7:30 AM Stephen Far
