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 ...

There will be an app for that: making random numbers on a mobile phone. (Courtesy: Marketa Michalkova) Do you feel nervous when you make a credit-card transaction using your mobile phone? Your worries ...

Researchers have devised a new kind of random number generator, for encrypted communications and other uses, that is cryptographically secure, inherently private and - most importantly - certified ...

Peter Bierhorst’s machine is no pinnacle of design. Nestled in the Rocky Mountains inside a facility for the National Institute of Standards and Technology, the photon-generating behemoth spans an ...

Using a single, chip-scale laser, scientists have managed to generate streams of completely random numbers at about 100 times the speed of the fastest random-numbers generator systems that are ...

Quantum physics can be exploited to generate true random numbers, which have important roles in many applications, especially in cryptography. Genuine randomness from the measurement of a quantum ...

Random number sequences are essential to a host of encryption schemes. But true randomness in the strict sense is not possible in the classical world; it only occurs in quantum-mechanical processes.
