  • At the headquarters of Cloudflare, in San Francisco, there's a wall of lava lamps: the Entropy Wall. They're used to generate random numbers and keep a good bit of the internet secure: here's how.
    Thanks to the team at Cloudflare - this is not a sponsored video, they just had interesting lava lamps! There's a technical rundown of the system on their blog here: blog.cloudflare.com/lavarand-...

    Two fun facts:
    -Tom didn't necessarily need to approach Cloudflare about filming in front of the lava lamps as Cloudflare encourages people to come pass by, take photos/videos, and even put on approved demonstrations or performances in front of the lamps, as that introduces further randomness.
    -Their London office has a machine that utilizes the RNG data their offices have produced to spit out receipts that contain random numbers, phrases, Magic 8-Ball responses, mazes, sudokus, and QR codes.

    The one in Singapore that uses a radioactive source really interested me. The pendulum and lava lamp are macroscale versions of the Singapore one in a way, and yet using radioactive decay to generate random numbers uses such fundamental physics. It's like they have directly linked their RNG to the fabric of reality itself. The code the universe was written in is effectively interfaced directly with cloudflare servers.

    When I was writing computer games in the 1970s, I used the memory refresh register as my source of random numbers. Since my games involved a lot of human interaction, there is was adequate variation in activity to ensure that different games had different outcomes. The refresh register cycles through the memory to keep it powered, and has a large number of values each second. A weakness of the register is that numbers are sequential, but using them as a seed to a pseudo random number generator give a range of values.

      You clearly don't understand chaos theory. Even if you had the EXACT lava lamp, and put the EXACT same bubble pattern in it, minute differences (your exact voltage heating the lamp, error in exactly approximating the lava lamp, a 0.001C difference in room temperature) would propogate and quickly have your "copy" diverge from what it is modeling.
      It's a CHAOTIC SYSTEM. What you are proposing is aakin to forecasting the weather, a decade in advance, from today's known data. There's NO POSSIBLE WAY you could know the data precisely enough to do that...you could be pretty damn accurate for a week, then chaos would rear it's ugly head. (You forgot to account for that one butterfly in Madagascar that flapped its wings.)

      The sad thing is people think they are safe using ssl when they are not. Browsers always have " security.ssl.require_safe_negotiation" off. For mozilla firefox, in the address bar type about:config then enter. Then type ssl into the search box. Then look for security.ssl.require_safe_negotiation . Change it from false to true.
      *just a warning. websites with bad security won't work anymore* . And Some ads may disappear. Some insecure ssl advertisements were used by foreign governments to hack everyone's internet browsers. I don't know if they still are

    One thing I thougth about is someone walking in front of the lamps changes it WILDLY. Also if some lamps die out (as lava lamps tend to do) it can be replaced whenever so long as a good majority are working. That also makes it harder to simulate since you don't know when a lava lamp will die.

      @klaxoncow 6 ปีที่แล้ว +53

      No, because the duplication would compromise the "randomness".
      Think about it. You're pointing your camera at the lava lamps, running an algorithm to get a random number - e.g. 4589237598236529870 - and then you send out that exact same number to 100 companies.
      They're all getting the exact same number.
      So let's say that you're getting this feed of random numbers and so am I. We both get the number 4589237598236529870 sent to us. You use it to create an encryption key. All I have to do is use the exact same algorithms as you and the encryption key I get will be exactly the same. Thus, I can break your encryption.
      You can't duplicate random numbers and hand out the same numbers to different people, because that makes them perfectly predictable. Whatever number you were given is exactly the same number I was given too.
      Thus, if you were doing this, then you could only sell your random numbers to a single company.
      Either that, or you couldn't send out the same number twice. But that has its own problems, in that you have to obtain a random number, send it out, obtain a new random number, send it out, and so forth. You'd be limited in the amount of companies and / or the rate at which you could send out numbers, simply because of the time it takes to "round robin" through all your customers to hand them each a unique random number.
      (To explain, imagine that it takes 0.1 seconds to take a picture, process it and produce a random number. You have 10,000 customers. So to "round robin" through all your customers, giving them each a unique random number would take 10,000 x 0.1 seconds = 1,000 seconds or 16.667 minutes. So one particular customer only gets 1 random number from you every 17-ish minutes. If they need a lot of random numbers for cryptography, then that rate would just be much too slow for them.)
      No, if you're serious about your random numbers for cryptographic purposes, you can't source them from the same place as anyone else.
      You need your own source of randomness.
      Like, ooh, a big wall of lava lamps, say.
      Sure, choosing to use lava lamps, that's "theatre" to generate publicity. But the fact that they own their own source of randomness like this to ensure that it's totally unique and can't be duplicated, that's perfectly sound and logical security.

      If your camera feed was timed wrong (due to network lag, different computer, etc.) by even a a fraction of a second you may not get the same random numbers. A very small variation in speed or very small deviation from their process for generating numbers from that many continuously moving lava lamps generating that long of a number would lead to failure because a 99% correct key would be useless.

    If some jerk put black cardboard over the camera, then it would mean the visual component would be the same black screen! Though I imagine Cloudlfare also uses more typical randomness functions in their algorythm and are really using the image just as part of the seed for the randomness (maybe the other part being the unix timecode), so that this kind of malfunction wouldnt straight-up result in the keys becoming the same, they would just temporarily become easier to figure out, and probably not for long enough for someone to breach it.
    I wonder if they used a low quality camera on purpose that gets a good layer of extra noise in its image or something?

Not ideal but it would still be at least somewhat random. Using a low-quality camera .... could actually be a decent solution, as it would indeed cause a lot of random colored pixels in the picture.
