Abstract
As is known to all, data transmission in wireless networks is easy to intercept because of the openness of wireless signals. In order to deal with this security problem, this paper presents a secure communication method based on driving-response synchronization and TCP protocol. The video signal is encrypted and decrypted by a chaotic sequence and transmitted through WIFI network in real time. Furthermore, the system configuration and design procedures are described in detail. Experimental results show that our approach is feasible for video secure communication.

Chaotic secure communication is mainly generated by chaotic sequences with good random performance
The system structure for realizing video signals encryption and decryption is shown in Figure 1, which can be divided into 3 parts
Summary
With the rapid development of mobile Internet, cloud computing, social networking, big data and other information technologies, the security of multimedia data has attracted more and more attention in recently years. The large amount of multimedia data and the strong correlation between adjacent elements make the traditional text encryption algorithm encounter severe challenges. To solve these problems, scientists have introduced chaotic secure communication technology into the transmission process of multimedia signals [1,2,3,4]. Chaotic secure communication is mainly generated by chaotic sequences with good random performance. It can be applied in multimedia encryption and decryption. The rest of this paper is organized as follows.
