Pseudo-random bit generator based on multim-modal maps

摘要

The present invention is related with a computer-implemented method for generating a pseudo-random bit generator including the steps: a. Defining a multi-modal map by the equation: ƒ_β=β(d_r+1−x)(x−d_r), x∈ℑ_r; b. Set the value of k∈⁺, and obtaining the values of β_j, for j=from at least 1, to the final value k by the following equations: β₁=4k; β_j=(j)(β₁); for 2≤j≤k; and taking the values of β_j and split the space into 2j regions δ₁^j, to δ_2j^j which are determined by values κ₁^j to k_(2j)−1^j.
