Learn about the best methods for testing random number generator algorithms, such as statistical tests, empirical tests, code analysis, and comparison and validation.

In the Swiss experiment, the camera was used to create a 1.25 Gbit/s stream of random numbers. One worry about any random-number generator is that the numbers could be influenced in a predictable way ...

Fast randomness A diagram of the quantum random number generator on the photonic integrated chip. (Courtesy: Bing Bai and Yao Zheng) Smartphones could soon come equipped with a quantum-powered source ...

For example, it would be better to use a random-number generator that produces a sequence of zeros, ones, and twos and then ignores the zeros to give a sequence of just ones and twos.

This avoids the risk of using numbers with little (or no) randomness for example to generate passwords, which hacker could then crack" professor Hugo Zbinden enthusiastically points out.

Although there are many ways to get a random number generator (RNG) set up on a microcontroller, it’s hard to argue with the sheer randomness of the various kinds of radiation zipping all around ...

However, Von Neumann’s approach was not a true random number generator as the sequence would eventually fall into a short repeated cycle of numbers, no matter what seed value was used to start with.
