Gotta love government IT projects. When you want to randomly pick airline travelers for reduced security screening, it makes sense to use a random number generator to choose those people, so you can ...

True random number generators (TRNGs) harness the inherent unpredictability of physical processes to produce random numbers crucial for cryptographic applications, secure communications, and various ...

To simulate chance occurrences, a computer can’t literally toss a coin or roll a die. Instead, it relies on special numerical recipes for generating strings of shuffled digits that pass for random ...

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 ...

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 ...

Researchers have come up with a way to generate truly random numbers using quantum mechanics. The method uses photons to generate a string of random ones and zeros, and leans on the laws of physics to ...
