A newly discovered set of mathematical equations describes how to turn any sequence of random events into a clock, scientists ...

Randomness is a slippery concept, defying precise definition. A simple example of a random series is provided by repeatedly tossing a coin. Assigning “1” for heads and “0” for tails, we generate a ...

A truly random number is something that is surprisingly difficult to generate. A typical approach is to generate the required element of chance from a natural and unpredictable source, such as ...

Do you feel nervous when you make a credit-card transaction using your mobile phone? Your worries could soon be a thing of the past, thanks to a low-cost device that could bring powerful cryptography ...

Random number generators in digital information systems make use of physical entropy sources such as electronic and photonic noise to add unpredictability to deterministically generated pseudo-random ...

There is a growing sense among physicists that all physical processes can be thought of in terms of the information they store and process; by some accounts information is the basic unit of existence ...

Constrained-random verification (CRV) offers a highly effective way to deal with the challenges of microprocessor verification. These verification challenges are overwhelming for many reasons: complex ...

Random numbers are a precious commodity, whether expressed as strings of decimal digits or simply 1s and 0s. Computer scientist George Marsaglia of Florida State University, however, likes giving them ...
