Latest Random number generation Stories

The widespread use of true random number generators (TRNGs) has taken a step closer following the creation of the most lightweight designs to date by researchers at Queen's University Belfast's Institute of Electronics, Communications and Information Technology (ECIT).Members of the Institute's cryptography research team have produced a series of circuits that are up to 50 per cent smaller than anything else currently available. Optimised for digital circuits, FPGA and ASIC, they push...

A simple device measures the quantum noise of vacuum fluctuations and generates true random numbersBehind every coincidence lies a plan - in the world of classical physics, at least. In principle, every event, including the fall of dice or the outcome of a game of roulette, can be explained in mathematical terms. Researchers at the Max Planck Institute for the Physics of Light in Erlangen have constructed a device that works on the principle of true randomness. With the help of quantum...

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 random by laws of physics.That is important because randomness is surprisingly rare. Although the welter of events that transpire in the course of daily life can certainly seem haphazard and arbitrary, none of them is genuinely random in the sense that they could not be predicted given...

WEST LAFAYETTE, Ind. -- If you wanted a random number, historically you could do worse than to pick a sequence from the string of digits in pi. But Purdue University scientists now say other sources might be better. Physicists including Purdue's Ephraim Fischbach have completed a study comparing the "randomness" in pi to that produced by 30 software random number generators and one chaos-generating physical machine. After conducting several tests, they have found that while...
