When a computer generates a “random” number, it goes through certain algorithms that will allow it to come up with that number, which means it wasn’t really random after all. Random numbers are ...

Computers are known to be precise and — usually — repeatable. That’s why it is so hard to get something that seems random out of them. Yet random things are great for games, encryption, and multimedia ...

A team of international scientists has developed a laser that can generate 254 trillion random digits per second, more than a hundred times faster than computer-based random number generators (RNG).

Cloudflare is one of those Internet companies you use all the time, but don’t usually know it. Big websites you visit use Cloudflare to shore up their defenses against denial of service attacks. The ...

Random numbers are crucial for computing, but our current algorithms aren’t truly random. Researchers at Brown University have now found a way to tap into the fluctuations of skyrmions to generate ...

Before computers and algorithms were developed to generate random numbers, there were dice. Middle Eastern tombs uncovered cubical dice dating back to the 20th century BC—but it’s believed they’re ...

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 ...

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 ...

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 ...

Whenever we need to communicate in secret, a cryptographic key is needed. For this key to work, it must consist of numbers chosen at random without any structure – just the opposite of using the ...
