    I’ve heard that you could pull random numbers from a basic thermometer. Is a hardware RNG just based on measuring the random noise of some measurement like that?

      This documentation from Intel says of the entropy source that “The ES runs asynchronously on a self-timed circuit and uses thermal noise within the silicon to output a random stream of bits at the rate of 3 GHz.” By thermal noise, I believe they mean this sort of noise but this is not my subject of expertise (I’m a programmer, not an EE or physicist). Not sure what AMD uses, but probably something similar, I’d expect.
