Weekend Reading from TechAptitude!

Get to know new Cryptography Standards (FIPS 20-3, FIPS 204, FIPS 205, FIPS 206) developed by NIST to withstand quantum attacks and prevent the so-called “Q-Day”. Q-Day is an estimate of the point in time when quantum computers will be able to reliably break existing RSA-2048 cryptography. https://techaptitude.substack.com/p/quantum-technologies-nist-drives #PQC #NIST #Cryptography #Q_Day #PostQuantumCryptography #Quantum #Encryption #CryptographyAlgorithms #TechAptitude

Graphic: TechAptitude Post on Quantum Standards

I've been wondering ... with the current drive to increase #Passkey adoption (which I support), as well as with the acceleration of #PostQuantum cipher adoption (often with a target of 2029), I believe there's a problem emerging. Passkeys/WebAuthn take some time to adopt, and there's a lot of organisational effort involved to get all the ducks in a row. As there doesn't seem to be a post-quantum resistant FIDO standard in place, yet (please, correct me if I'm wrong), they **would have to go about it again.** There does not seem to be any cryptographic agility in the system at present. Particularly with PQC hardware tokens (Yubikey, @nitrokey and others) unavailable at present, this will become even more difficult.

How do others see this?

I'd love to have a bit more knowledge on long term sustainability of the efforts in migrating on a broader basis towards Passkeys.

It’s happening this Saturday in Rome: #PQCSA Workshop on Post‑Quantum Cryptographic Protocols (#Eurocrypt 2026)!
Organized by COSIC (KU Leuven), we’re excited to share PQC knowledge with 120+ participants.
See you there! 😁

Scott Aaronson (congrats on induction to Nat’l Academy of Sciences!) being extremely clear in his latest post:

“And I’d say that that makes my own moral duty right now ironically simple and clear: namely, to use my unique soapbox, as the writer of The Internet’s Most Trusted Quantum Computing Blog Since 2005(tm), to sound the alarm.

So, here it is: *if quantum computers start breaking cryptography a few years from now, don’t you dare come to this blog and tell me that I failed to warn you. This post is your warning.* Please start switching to quantum-resistant encryption, and urge your company or organization or blockchain or standards body to do the same.”

RE: https://mastodon.social/@lobsters/116489926392138691

This is super interesting. In a way, it's fulfilling the security requirement given by a cryptographic hash (digest), but allows this to work on systems requiring a cryptographic signature (ECDSA).

However, too bad it's not cryptographically agile, so won't work in a #PQC world.

Cloudflare aims for full post-quantum security by 2029, including authentication across all services. Current post-quantum encryption protects most traffic, but PQ-vulnerable keys must be retired to prevent downgrade attacks. 🔐

Google bumps up Q Day deadline to 2029, far sooner than previously thought

Google is dramatically shortening its readiness deadline for the arrival of Q Day, the point at which existing quantum computers can break public-key cryptography algorithms that secure decades’ worth of secrets belonging to militaries, banks, governments, and nearly every individual on earth
