In this work we present a model for computing the random processes in digital computers which solves the problem of periodic sequences and hidden errors produced by correlations. We show that systems with non-invertible non-linearities can produce unpredictable sequences of independent random numbers. We illustrate our results with some numerical calculations related to random walks simulations.

Key words: random number generator, independent random numbers
