    This office needs a parking garage.
    Why the fuck are americans always building 2 dimensional except for their buildings???

        Even our local grocery store that is probably ¼ of the size of a typical Walmart (Edeka center in Germany) has a 2 story parking deck and another underground parking garage under the literal store.

        Edit: To answer to your comment: This has theme park level parking. They should install a round trip subway under or surface tram at the place

      Because they have the space. It’s hard for us Europeans to understand. In places where they don’t, they certainly go below ground - look at Microsoft’s parking garage in Redmond.

    Daniel Bernstein at the University of Illinois Chicago says that the US National Institute of Standards and Technology (NIST) is deliberately obscuring the level of involvement the US National Security Agency (NSA) has in developing new encryption standards for “post-quantum cryptography” (PQC).

    This sentence is basically all.

    So I wrote a long-ass rundown of this but it won’t post for some reason (too long)? So TLDR: this is a 17,600-word nothingburger.

    DJB is a brilliant, thorough and accomplished cryptographer. He has also spent the past 5 years burning his reputation to the ground, largely by exhaustively arguing for positions that correlate more with his ego than with the truth. Not just this position. It’s been a whole thing.

    DJB’s accusation, that NSA is manipulating this process to promote a weaker outcome, is plausible. They might have! It’s a worrisome possibility! The community must be on guard against it! But his argument that it actually happened is rambling, nitpicky and dishonest, and as far as I can tell the other experts in the community do not agree with it.

    So yes, take NIST’s recommendation for Kyber with a grain of salt. Use Kyber768 + X448 or whatever instead of just Kyber512. But also take DJB’s accusations with a grain of salt.

      Honestly at this point… I’d be surprised if they are seriously undermining encryption. NIST and NSA need encryption to work to protect the government itself … they’re to my knowledge not staffed by idiots, and a lot has changed since the 90s and early 2000s. Encryption is a core portion of security in 2023.

    I was curious to hear what argument they were making but the article is behind a paywall. Could someone with access to it summarize for me?

    I am curious because this seems a bit implausible to me given that the protocol selection process involves an open competition.

      Really. I hope everyone saw this coming. The process has also been weirdly slow. I’m not sure why everyone is waiting up for NIST.

      Thankfully, PQ HTTPS is just around the corner now, and I imagine other TLS-based protocols won’t be far behind.

        That is the problem with encryption. It only provides security over a period of time. Always better to keep data on your own hardware in your own place.

        Quantum is also more of an issues for public key crypto. Symmetric key crypto is different.

            Asymmetric key exchange works by utilising a complex math equation involving massive exponents that is easy to run to get an answer, but very hard to use that answer to get the numbers you started with.

            With traditional computers, you essentially need to try every combination of numbers through trial and error to get the starting values.

            Quantum computers are almost purpose built for this kind of math and can solve those types of problems exponentially faster than traditional computers.

            However, for a symmetric key, there isn’t an exchange that can be attacked, both sides already know the key.

            Others know a lot more about this then I do. The short answer is that some problems that are hard to solve now can be easily solved with quantum computers. Factorization of large integers is one of those things that is easily solved and public key crypto is based on that sort of problem. Hence the panic. Symmetric key crypto is not.

            I think it comes down to just because quantum computers can solve some problems easily it does not mean they can solve all problems easily. Each situation needs to be looked at.
