A chaotic secure communication method based on chaos systems partial series parameter estimation

Abstract

We proposed a chaotic secure communication method, namely the partial series of the chaos system for parameter estimation and the other series for secure communications. Parameter estimation could be obtained from the partial series of chaos system with the chaotic ant swarm optimization algorithm, to understand all of the information of the chaos system. In the process of parameter estimation, the introduced parameter space and ant swarm space transformed into each other through space transformation function. Numerical simulation validated the feasibility of the chaos system partial series parameter estimation and the chaotic secure communication method.
