摘　　要：随着网络和多媒体技术的快速发展,信息安全技术成为了人们关注的一个热点课题。图像视频信息保密通信是混沌应用的一个新领域,混沌加密在计算机网络和视频通信方面的应用为解决信息安全问题开辟了一种新的途径。根据一个离散时间混沌序列,运用驱动—响应式同步方法对视频数据进行实时加密和解密,最后通过Wi Fi网络传输实现了无线混沌视频保密通信。With the rapid development of networks and multimedia technology, information security technology has become a hot topic of concern. Secure communications on video information is a new field of chaos application. Utilizing chaotic encryption in computer networks and video communication has opened a new approach for solving information security. In this paper, according to a discrete - time chaotic sequence, the drive - response synchronization method is applied to encrypt and decrypt video information in real - time. Finally, the WiFi network has been considered for the implementation of wireless chaotic video secure communications.
