Today this post is going around on the internet and there someone wrote that it could perhaps mean that elliptic curve crypto will be weakened.

Here's the link: https://plus.google.com/+DavidRoberts/posts/KcjNn99tYaa

Can someone perhaps clarify this?

The result announced by Taylor has absolutely nothing to do with elliptic curve cryptography, and no effect thereon.


+1 to @pepite for reading to the bottom of the thread where any relation to cryptography was dispelled.

Even if a new basic result like this was discovered that slightly weakens ECC, it would take some time to figure out how to use it in an attack. Such an attack would likely not "break" ECC, just weaken it slightly.

I'll bet you random internet points that quantum computers will completely and thoroughly destroy ECC first!

  • $\begingroup$ @Elias No, nothing concrete, but I'm reminded of a talk Dan Bernstein gave about "exploring Attack Mountain of combining congruences"; knowing that this is a powerful cryptanalytic technique does not give us an obvious path to the summit, or even a way to tell when we've reached the summit. I suppose other basic insights are more directly applicable, so time-to-attack depends on the insight. $\endgroup$ Jan 27, 2017 at 14:41
