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 ...

RANDOMNESS IS A valuable commodity. Computer models of complex systems ranging from the weather to the stockmarket are voracious consumers of random numbers. Cryptography, too, relies heavily on ...

Strong passwords are needed to protect your electronic accounts from brute force attacks and other cyberattacks attempted by hackers. In this article, I am going to show you how you can generate a ...

Randomness rules the very fabric of reality. So it only makes sense that scientists have figured out how to use nature’s randomness as a tool in our mundane world. Random numbers go hand-in-hand with ...

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 ...

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 ...

Using the inherent quantum flickering of empty space, researchers have figured out how to generate random numbers at an unprecedented rate. The record-breaking method could be used to enhance ...

Because computers don't understand words or phrases in the same way people can, they speak a language of their own, using only two symbols: 0 and 1. This computing parlance is known as binary code, ...

While world events are often difficult to predict, true randomness is surprisingly hard to find. In recent years, physicists have turned to quantum mechanics for a solution, using the inherently ...
