Re: Using just a laptop, an encryption code designed to prevent a quantum computer attack was cracked in just 53 hours | Science & Tech | EL PAÍS English Edition

Yeah that's Rainbow, one of the NIST round 3 finalist signature schemes.

Not too surprised it was broken, as it uses extension fields which I 
have never trusted, they have too much (unused) structure.
