Infinite Noise True Random Number Generator
https://www.electronics-lab.com/infinite-noise-true-random-number-generator/
waywardgeek @ github.com shares his USB TRNG: The Infinite Noise TRNG is a USB key hardware true random number generator. It uses what I call a “Modular Entropy Multiplier” architecture (previously Infinite Noise Multiplier or FireBug). Besides being simple, low-cost, and fast, it is much easier to get right than other TRNGs. It naturally defends […]
