Laser trick churns out secure random numbers

Description

Generating random numbers is harder than you might think, and the security of digital communications depends on it.

Now a new method that uses lasers to produce streams of truly random numbers faster than ever before could help improve security at a time when digital traffic and cybercrime are both growing.

. . . . .

The new system can generate truly random numbers 10 times faster than existing devices, which can typically only produce 10s or 100s of megabits of random numbers per second, says Atsushi Uchida, an electrical engineer at Saitama University, Japan.
