IEEE Spectrum – Engineers in Taiwan say they’ve invented a tiny low-power circuit based on memristors that could improve the security of data transmission over the Internet and of using Near Field ...

Peter Bierhorst’s machine is no pinnacle of design. Nestled in the Rocky Mountains inside a facility for the National Institute of Standards and Technology, the photon-generating behemoth spans an ...

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 ...

Researchers have developed a chip-based quantum random number generator that provides high-speed, high-quality operation on a miniaturized platform. This advance could help move quantum random number ...

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 ...

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 ...
