Chaos-Based Engineering Applications with a 6D Memristive Multistable Hyperchaotic System and a 2D SF-SIMM Hyperchaotic Map

In recent years, the research of chaos theory has developed from simple cognition and analysis to practical engineering application. particular, hyperchaotic systems with more complex changeable chaotic characteristics are sensitive unpredictable, so they widely used in fields. this paper, two important applications based on hyperchaos pseudorandom number generator (PRNG) image encryption studied. Firstly, coupling 6D memristive system a 2D SF-SIMM discrete mapping as double entropy source structure. The structure can realize new PRNG that meets security requirements, which pass NIST statistical test when XOR postprocessing method is used. Secondly, structure, algorithm proposed. uses diffusion-scrambling-diffusion scheme conversion original plaintext ciphertext image. Finally, we analyze proposed mechanism, respectively. results show good output high security, be effectively applied field information system.
