Lotteries, accidents and rolls of dice — the world around us is full of unpredictable events. Yet generating a truly random series of numbers for encryption has remained a surprisingly difficult task.

An international team of physicists has created the first system that can produce verifiably random numbers. The technique relies on the inherent uncertainties in quantum mechanics and future versions ...

When it comes to unpredictable strings of numbers, some are more random than others. Until now there has been no way to confirm 'true' randomness, leaving encryption techniques that rely on random ...
