Mathematician warns NSA may be weakening next-gen encryption::Quantum computers may soon be able to crack encryption methods in use today, so plans are already under way to replace them with new, secure algorithms. Now it seems the US National Security Agency may be undermining that process

Is that what they're talking about?

Yes

But one-time pads aren't impractical like they said?

[–] [email protected] 5 points 1 year ago

One-time pads are impractical because the sender and the target need to meet up beforehand and agree on a code, and no one else should know this code. With modern encryption, this is not necessary. The target can come up with both the encryption and decryption algorithms, and send only the first to the sender publicly.
