A Novel Method of Pseudorandom Sequence Design Based on Hyperchaos System

摘要

Compared with low-dimensional chaos system, Hyperchaos system has excellent security in communication because Hyperchaos sequence has better complexity and randomicity. The thought is proposed that Hyperchaos sequence is applied to Design the pseudorandom sequence after decreasing its dimension, then the novel algorithm is proposed, and the thorough analysis and research are carried on to verify Hyperchaos sequence's capability. Study shows that the novel chaos pseudorandom sequence has good complexity and well-proportioned stochastic diffusion. A novel stochastic sequence design method is achieved.
