Comparison of hardware random number generators

From Wikipedia, the free encyclopedia
Jump to: navigation, search

In computing, a hardware random number generator is an apparatus that generates random numbers from a physical process. Such devices are often based on microscopic phenomena that generate a low-level, statistically random "noise" signal, such as thermal noise, the photoelectric effect or other quantum phenomena.
