Abstract: In this brief we propose two pseudo-random number generators (PRNGs) based on the discrete Arnold cat map (DACM) over the integer ring $\mathbb {Z}_{2^{m}}$ . The first PRNG employs ...

Random numbers are very important to us in this computer age, being used for all sorts of security and cryptographic tasks. [Theory to Thing] recently built a device to generate random numbers using ...

Online color prediction games have become a widely popular form of mobile entertainment, attracting millions of players with their simplicity and suspense. While the mechanics appear ...

Eeny, meeny, miny, mo, catch a tiger by the toe – so the rhyme goes. But even children know that counting-out rhymes like this are no help at making a truly random choice. Perhaps you remember when ...

AMD has officially confirmed a high-severity security vulnerability in its new Zen 5–based CPUs, and it’s a nasty one because it hits cryptography right at the source: the hardware random number ...

Random number generation, or RNG, is the unseen engine that makes many video game features work, from loot drops to procedural levels. Figuring out how it works helps you understand why you never seem ...

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 ...

Scientists at NIST and the University of Colorado Boulder have created CURBy, a cutting-edge quantum randomness beacon that draws on the intrinsic unpredictability of quantum entanglement to produce ...

Trust, but verify: Random number generation is a serious matter in modern computing. Most systems rely on a purely hardware-based approach to RNG, but the process is essentially impossible to verify ...
