Research on the security protection based on spatiotemporal chaos technology for the video resource of network education

摘要

The network technology, multimedia technology and communication technology are widely used in all kinds of education areas. The network-teaching is a novel application result for higher education in the information age. However, it is an increasingly outstanding problem for the management and security in the resource library of the network teaching and education. By the characteristics of chaotic theory and encryption, in this paper, a kind of secure communication system based on spatiotemporal chaos is designed and exploited for solving the security protection problem of network-teaching video resource. By using Visual C++ platform, an illustrative example is realized and its experimental results demonstrate that the online video-teaching resource is protected very well during the encrypted transmission based on the spatiotemporal chaotic technology.
