Coding or decoding method of generating method and the data stream of pseudo-random sequence

摘要

The present invention is a method for coding a first data stream and a method for decoding a second data stream, wherein the coding is a third data stream formed by the first data stream and a pseudo-random sequence. It relates to a method, which is the result of a comparison with an exclusive comparison operation (XOR) with a data stream. In particular, the present invention relates to a method based on a hyperchaotic coding method for generating pseudo-random sequences used in coding and decoding.
