Secure Communication Method of Metallurgical System Data Network based on Chaotic System Sequence Parameter Identification

In the research process of chaotic system sequence parameter identification, we find that there is only one chaotic attractor in chaotic direct spread spectrum signals, which cannot satisfy the confidentiality of communications. Based on the thought of generalized synchronization of chaotic system, we proposed a chaotic secure communication method, in other words, the partial sequences of chaotic system were used for the parameter identification of chaotic system. The chaotic ant colony optimization algorithm was used for the parameter identification of partial sequences of chaotic system, so as to achieve the purpose of understanding all the information of chaotic system. The parameter space and the ant colony space were introduced into the parameter identification process. We used the space transformation function to transform the parameter space and the ant colony space. Experimental results show that using the Lorenz system numerical method can verify the feasibility of chaotic system partial sequence parameter identification and chaotic secure communication.
