- Cryptographic Random Numbers
 - Introduction to random numbers used for cryptography and digital security applications. Learn about criteria for randomness, random sources, and advice about what to do and not to do with random number generators. - Hardware Random Number Generators
- 2000 paper about the testing and applications of hardware or true random number generators. Discusses the way hardware generators differ from pseudorandom ones. From Statistics Research Associates.
- High-Entropy Randomness Generator
- 2002 research paper discussing the principles of a High-Entropy Randomness Generator. Suggests ways such a random number generator could be used in cryptography and other high-stakes adversarial applications.
- How to Generate Pure Random Numbers
- Learn about the differences between pure random numbers and pseudo-random ones. Discusses pseudo-random number generators, what it means for a number to be non-deterministic, and the sources of natural randomness.
- LavaRND
- Downloadable pseudo-random number generator. The LavaRND generator is seeded with a seven-way cryptographic hash of a digitization of a chaotic system, or, in other words, a digital picture of six Lava Lite Lamps.
