Generating a string of random numbers is easy. The hard part is proving that they’re random. As Dilbert creator Scott Adams once pointed out, “that’s the problem with randomness: you can never be sure ...

Randomness is incredibly useful. People often draw straws, throw dice or flip coins to make fair choices. Random numbers can enable auditors to make completely unbiased selections. Randomness is also ...

In the digital world, there is no such thing as a perfect roll of ...

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 ...

In this work, we present a study of a quantum random number generation system based on a branching path approach with spatial superposition principle, realised using fibre optics. The analysis of the ...

Randomness can be a Good Thing. If your system generates truly random numbers, it can avoid and withstand network packet collisions just one of many applications. Here's what you need to know about ...

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 ...

Security company RSA was paid $10 million to use the flawed Dual_EC_DRBG pseudorandom number generating algorithm as the default algorithm in its BSafe crypto library, according to sources speaking to ...

Your job is to create a random number generator. Your device starts with a speaker and a membrane. On this membrane will sit a handful of small, marble-size copper balls. An audio source feeds the ...
