In the Swiss experiment, the camera was used to create a 1.25 Gbit/s stream of random numbers. One worry about any random-number generator is that the numbers could be influenced in a predictable way ...

How can you generate random bits? Some people think it’s not easy, others will tell you that it’s pretty damn hard, and then there are those who wonder if it is possible at all. Of course, it… ...

That means that even if some enemy understands everything about how the random number generator works, they still can’t predict the outcome.

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 ...

A perfectly provable random number generator is the bedrock of good cryptography. This scientist wants to make one.

How to make a quantum random-number generator from a mobile phone As a bonus, the research team managed to construct their experiment using affordable off-the-shelf components – a feature that allowed ...

A new laser’s chaotic light beam lets the device generate multiple number sequences at once, similar to throwing multiple dice at a time.

The reaction of the lamps is unpredictable, and this allows them to generate really random numbers. [Joshua], a Cloudflare employee, talks about the technical details of the system in a recent ...

Researchers have built the fastest random-number generator ever made, using a simple laser. It exploits fluctuations in the intensity of light to generate randomness—a coveted resource in ...

Random numbers are increasingly important to our digitally connected world, with applications that include e-commerce, cryptography, and cloud computing. Producing a large amount of truly random ...
