Abstract
In this paper, the dynamic characteristics of four-dimensional discrete hyperchaotic mapping are analyzed by phase diagram, bifurcation diagram, Lyapunov exponential spectrum and permutation entropy complexity. On this basis, a new hyperchaotic pseudo-random sequence generator is designed by using the four-dimensional discrete hyperchaotic sequence and multi-quantization algorithm. The performance of the hyperchaotic pseudo-random sequence generator is tested by NIST SP800-22 and sequence correlation. The test results can indicate whether the sequence generated by the chaotic pseudo-random sequence generator has good randomness and correlation. The research results in this paper will provide theoretical basis and experimental basis for the application of chaotic pseudo-random sequences in information security fields such as secure communication.
