🔒 Oh, the irony! An article on "Quantum Cryptography" that's as #cryptic as the topic itself. Apparently, understanding #QKD requires more clearance than a James Bond mission. 🚀🔑

Fun post pointed out by Werner Koch on the GPG "post-quantum defaults" thread:

https://www.metzdowd.com/pipermail/cryptography/2026-March/039449.html

"""
Quantum Cryptography, while intellectually neat, does not present a
practical attack that we need protection against at this time.
Kleptographic Standards on the other hand are very much a practical
attack that we need to protect against at this time.

When a standards body tells you that you should cast aside well-studied
cryptographic algorithms which have earned their trust through dozens of
years of examination, testing, and motivated attackers, for the sake of
protection against Quantum Crypto? The attack you should be protecting
against isn’t Quantum Crypto.

[Cryptography] It's probably kleptography.

Quantum computers need vastly fewer resources than thought to break vital encryption

No, the sky isn't falling, but Q Day is coming, and it won't be as expensive as thought.

Inventors of Quantum Cryptography Win Turing Award - Schneier on Security

Charles Bennett and Gilles Brassard have won the 2026 Turing Award for inventing quantum cryptography. I am incredibly pleased to see them get this recognition. I have always thought the technology to be fantastic, even though I think it’s largely unnecessary. I wrote up my thoughts back in 2008, in an essay titled “Quantum Cryptography: As Awesome As It Is Pointless.” Back then, I wrote: While I like the science of quantum cryptography—my undergraduate degree was in physics—I don’t see any commercial value in it. I don’t believe it solves any security problem that needs solving. I don’t believe that it’s worth paying for, and I can’t imagine anyone but a few technophiles buying and deploying it. Systems that use it don’t magically become unbreakable, because the quantum part doesn’t address the weak points of the system...
