Mads Haahr, moderator and operator of random.org, a random number generator, wrote in an e-mail that Internet data encryption is one of the most common applications of random numbers.

That’s why we need a TRNG (True Random Number Generator), but that requires special hardware. Some high-end microprocessors are equipped with an internal hardware TRNG, but it is, unfortunately ...

But the random number generator they built was, they reasoned, still useful. So Haahr made it public at random.org, where it has been churning out random numbers ever since. It gets a lot of visitors.

The company needed some truly random numbers for its security solutions, so it turned to some groovy old tech: lava lamps. In their office is a wall of 100 lava lamps monitored by cameras.

The Random Number Generator is a tool that could be useful for genearting encryption keys for secure communications between activist organizations, or anyone concerned with privacy and security. From ...

The best we can do is to generate long sequences that have some of the key properties of random numbers. The programs that do this are called pseudo-random number generators.

A new random number generator that uses a micro laser developed by researchers at NTU Singapore is a hundred times faster than computer-based systems.

In computer security, random numbers are crucial values that must be unpredictable—such as secret keys or initialization vectors (IVs)—forming the foundation of security systems. To achieve this, ...
