Entropy Engine
Entropy Engine and NetRandom are the products of a collaboration between Los Alamos National Laboratory and Whitewood Encryptions Systems. Entropy Engine is the first truly random number engine, rather than pseudo-random. The technology utilizes the randomness of photons, making it verifiably random. Entropy Engine can be utilized on local devices, and with the help of NetRandom, also on networks.
