Random number generators aren’t just some niche toy of interest only to mathematicians. They’re also crucial to keeping our computer systems safe from hackers and those who would seek to do us harm.

A software routine that produces a random number. Used in applications such as computer games and cryptographic key generation, random numbers are easily created in a computer due to many random ...

To simulate chance occurrences, a computer can’t literally toss a coin or roll a die. Instead, it relies on special numerical recipes for generating strings of shuffled digits that pass for random ...

Researchers have built the fastest random-number generator ever made, using a simple laser. It exploits fluctuations in the intensity of light to generate randomness—a coveted resource in applications ...

If your name gets picked for jury duty, it’s because a computer used a random number generator to select it. The same goes for tax audits or when you opt for a quick pick lottery ticket. But how can ...

In a new paper in Nature, a team of researchers from JPMorganChase, Quantinuum, Argonne National Laboratory, Oak Ridge National Laboratory and The University of Texas at Austin describe a milestone in ...

Many popular random number generators (RNGs) are based on classical computer algorithms and have the advantage of being fast and easy to implement. The best examples pass many statistical tests ...

Generating random numbers might seem like a trivial task, that is until the numbers need to be truly random for cryptography or security reasons. When that’s the case, it turns out that these numbers ...

Whether it’s a game of D&D or encrypting top-secret information, a wide array of methods are available for generating the needed random numbers with high enough entropy for their use case. For a ...

Researchers have developed a chip-based quantum random number generator that provides high-speed, high-quality operation on a miniaturized platform. This advance could help move quantum random number ...
