  • Danitos@reddthat.comtoTechnology@lemmy.world•Your Cryptography Conspiracy Theory Is Wrong - Dhole MomentsEnglish

    Excellent post, like usual with Dhole, but I feel the defense of NIST/NSA push on non-hybrid Post-Quantum Cryptography (PQC) is weak. I think the author’s arguments boil down to:

    1. NSA is pushing to use it themselves, so why would they use a scheme they know it’s unsafe.
    2. There’s no mathematical space to leave a NOBUS backdoor.
    3. Peter Schwabe, main author of ML-KEM, used to work with Bernstein and was his Ph.D student.

    My responses are:

    1. They very link they used for 2., says: “[NSA is] using double encryption already.”, so they really wouldn’t be using pure non-hybrid PQC, as opposed to how they intend the rest of us to use.
    2. The same could have been said about SIKE (another non-hybrid PQC proposal), yet it was found to be insecure. Furthermore, author of the cited blog with the mathematical argument for 2. works for Google, so she has a conflict of interest in the topic. However, I’m not an expert on the topic, so the mathematical arguments are beyond me.
    3. I get it that Bernstein has a toxic attitude, and thus a toxic community that follows him, so I guess this was added to shut up a lot of incoming toxic responses that simply link to Bernstein’s blog. But yet, I can only see this as such an irrelevant tangent to dismiss criticism.

    Fun fact: you van use something similar to explain the law of ideal gasses:

    PV=nRT

    so if you increase Volume and keep the other variables constant, Temperature should increase. Now blow air out of your mouth with a small lip’s aperture, and you get cold air; try the same with open lips and you get hot air.

    Note: this is an oversimplification of the process, but the principle remains.
