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.

Random number sequences are essential to a host of encryption schemes. But true randomness in the strict sense is not possible in the classical world; it only occurs in quantum-mechanical processes.

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 ...

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 ...
