    AI Lattice Proofs with Chris Peikert

    The robots are at it again, and this time they’re solving, and breaking(?), math and cryptography! Things have been happening in the lattice corner including new leapfrogging complexity results in the closest vector problem (CVP), AND a possible poly-time quantum attack against the dihedral coset problem (DCP) that made everyone freak out for about a week (UPDATE: looks like it’s busted: https://eprint.iacr.org/2026/1693). ALSO, there was an important distinguisher attack against Classic McEliece, which on its face doesn’t sound like a big deal, unless you’re familiar with the track record of efficient distinguishers in the history of code-based cryptography… 😱 To help us make sense  of all this we are joined again by OG friend of the pod Chris Peikert! We had trouble with his audio but tried our best to fix it, apologies.

    An Odyssey of Lattice Cryptography with Mark Schultz-Wu

    We invited Mark Schultz-Wu on the podcast to talk about the history of lattice cryptography. When lattices are explained in plain english, they are actually quite simple! I don't think any of us have ever seen Deirdre so happy. If you're watching the video version, there's a section that's 6.1 minutes long with no cuts and consists just of Deirdre vigorously agreeing with what Mark is saying while smiling. What a time to be alive. Anyway, we are hosting another happy hour in Vegas between Black Hat and DEF CON! It's sponsored by Teleport! Thank you to Teleport, and dear readers, you should go check them out. Check out our socials or the podcast site to register.

    Trump's Golden Post-Quantum EO(s)

    The dear leader has actually bleated out some not-dumb executive orders (EOs) to accelerate adoption of post-quantum crypto for the US government! This looks to be in response to a flurry of advancements in quantum computing and quantum attack algorithms a few months ago. We cram legalize into our eyeballs— plus, ECDSA.fail!

    Python Cryptography Breaks Up with OpenSSL with Paul Kehrer and Alex Gaynor

    The Python cryptography module, pyca/cryptography, has mostly been a sane wrapper around a pile of C, so that users get performant cryptography on the many, many platforms Python targets. Therefore its maintainers, Alex Gaynor and Paul Kehrer, have become intimately familiar with OpenSSL. Recently, they declared that after many years of trying to make it work, they announced pyca/cryptography would be moving away from OpenSSL when supporting new functionality and exploring adding other backends instead. We invited them on to tell us about what has happened to OpenSSL, even after the investments and improvements following Heartbleed. No guests on this pod represent anyone besides themselves.

    The IACR Can't Decrypt with Matt Bernhard

    The International Association of Cryptologic Research held their regular election using secure voting software called Helios…and lost the keys to decrypt the results, leaving them with no choice but to throw out the vote and call a new election. Hilarity ensues. We welcome special guest Matt Bernhard who actually works on secure voting systems to explain which bits are homomorphically additive or not.
