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.

Random.org also offers a two premium services: A Third-Party Draw service for lotteries, raffles, etc.; and a Premium Generator that allows for the generation of “up to 10,000 unique numbers ...

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 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 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 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.

Current methods of generating random numbers can produce predictable results. Researchers said the new method could generate higher-quality random numbers with less computer processing.

These protocols can generate truly random numbers, but they still require a large amount of post-processing computational power to certify that the sequences are random.

Researchers from UNIGE have developed a new random numbers generator based on the principles of quantum physics. This physical theory shows that certain physical events occur perfectly at random ...
