I think in cryptography you are officially famous if you are remembered by only one letter (RSA, BLS, GPV, GHS, MOV, KLPT etc.) :)

the point is that you don't need to wait for a QC before PQcrypto becomes relevant. If someone stores all the communications today (easy!) and gets access to a QC in 20-30 years, they will be able to decrypt everything then. This is an issue for data that need to remain secret.

Solving TSP is easy. Solving TSP in polynomial time is hard and this paper does not claim that (there is a mention about a polynomial speed-up but that is not that important )

Dear academics and non-academics, I’d love to give a modest talk called "Three Little Stories on 3-Torsion"! 🎉 I'll cover insights from eprint.iacr.org/2020/1310, eprint.iacr.org/2024/201, and a new little cute result. Interested in some fun cryptography and math? Let’s chat! 😄

If you've been following the quantum thing, you've heard that *lattice-based crypto* is going to protect us against quantum attack. But what are they? And why are the keys so big? Why do we think they're secure? Christopher Patton wrote a great blog featuring special guest Peter Schwabe
