  This paper presents the physical concept and test results of sample data of
the high-speed hardware true random number generator design based on typically
used for High Energy Physics hardware. Main features of this concept are the
high speed of the true random numbers generation (tens of Mbt/s), miniature
size and estimated lower production cost. This allows the use of such a device
not only in large companies and government offices but for the end-user data
cryptography, in classrooms, in scientific Monte-Carlo simulations, computer
games and any other place where large number of true random numbers is
required. The physics of the operations principle of using a Geiger-mode
avalanche photo detector is discussed and the high quality of the data
collected is demonstrated.
