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

If this is true, NSA might be shooting themselves in the foot when they inevitably have to deal with Russia and China.
Just a guess, but I think they’re less concerned about the giant country’s surveillance of us, and more concerned about not being able to surveil the little terrorist cells.
or you know conversations with your healthcare providers
They probably consider that they overall lose more with strong cryptography, than the risk of other countries intercepting US communications. They must have other solutions in place to protect confident information. But they likely struggle with encryption being so widely used by anyone. Even granmas can now cover their communications without much effort
From what it sounds like, he’s not saying the algorithm is compromised itself, but rather that NIST is recommending a weaker version of it as sufficiently safe at (possibly) the request of the NSA. If that is the case we would know for sure pretty quickly once DISA updates their STIGs for internal use to include quantum resistant encryption. If the STIGs say to use a stronger version than NIST recommends then he was right.
And who is surprised by this? This is basically the NSA doing their job, nothing else.
There is no such thing as unbreakable encryption. If you want to hide a message, hide it at the source with the way you phrase things. I still have to buy weed illegally, and I use Signal, but I don’t tell the person I buy it from, “hey, I want a half-ounce of weed and I’ll pick it up on Friday at 2 pm,” I say something like, “hey, are you free this weekend?” And then they’ll say something like, “yeah, do you want to get your usual thing?” and then we’ll arrange a time.
And yes, I see the irony about talking about buying weed illegally when someone could potentially find out who I am on Lemmy.
True encryption does exist, it’s just that the encryption key is equally as long as the message itself which shows how impractical it is: if you have a method secure enough to send an encryption key of length X, why not just send the actual message of length X?
That’s interesting. I’ve never heard that before. Do you have more information I can read about somewhere?
Is that what they’re talking about?
Yes
But one-time pads aren’t impractical like they said?
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.
