You know two-factor authentication tokens, the ephemeral, six-digit numbers you use as a second layer of security when logging into, say, your email? Those constantly updating, randomly generated ...

Randomness sits at the heart of everything we do online. Many encryption algorithms depend upon randomly generated numbers to work, and that’s just one example of many. But how random is random? It’s ...

A new network paradigm can generate meaningfully random numbers—and fast. In network encryption, randomness has huge value because it’s not “solvable” by hackers. Classical computers can’t be ...

Sometimes you need random numbers — and properly random ones, at that. Hackaday Alum [Sean Boyce] whipped up a rig that serves up just that, tasty random bytes delivered fresh over MQTT. [Sean] tells ...

For many years, the serial numbers on Apple products have followed a predictable pattern, meaning you could use them to determine the precise model (including colour and storage capacity), and where ...

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 ...

Random numbers are increasingly important to our digitally connected world, with applications that include e-commerce, cryptography, and cloud computing. Producing a large amount of truly random ...

Even though rand() may be a good enough random number generator for making a video game, the patterns of random bits it spits out may not be sufficient for applications requiring truly random data.

America's greatest unsolved code leads to a $60million treasure - but no one has been able to crack it for 180 years. The mystery of the Beale ciphers begins in 1885, when a small pamphlet with three ...
