WEST LAFAYETTE, Ind. – If you wanted a random number, historically you could do worse than to pick a sequence from the string of digits in pi. But Purdue University scientists now say other sources ...

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 ...

Samsung has a solid track record with smartphone security, but it has upped the ante with its latest offering: the Galaxy Quantum 2. This includes something called a quantum random number generator ...

Researchers have developed a chip-based quantum random number generator that provides high-speed, high-quality operation on 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 ...

In September 2013, whistleblower Edward Snowden revealed that American and British intelligence agencies had successfully cracked much of the online encryption internet users used to keep their ...

Prime numbers are sometimes called math’s “atoms” because they can be divided by only themselves and 1. For two millennia, ...

There are a great variety of ways to build a random number generator, and similarly many ways to generate numbers that appear random, but in a pure mathematical sense generally aren’t. [Daniel Valuch] ...

Most password managers include a tool for generating random, strong passwords, but not all are created equal. Understanding the differences can help you make an informed choice. When the IBM PC was ...
