基于混沌技术的网络教育资源库安全保护研究

RESEARCH ON THE SECURITY PROTECTION FOR THE RESOURCE OF NETWORK EDUCATION BASED ON CHAOS TECHNOLOGY

根据混沌理论和混沌安全技术的特点,针对教学素材安全管理,提出了基于混沌的数字水印技术;针对资源安全访问系统,设计了基于混沌的OPT认证技术;并采用基于混沌的视频实时保密通信技术,应用于在线视频课堂教学系统。各项实验结果显示混沌技术在教育资源保护应用中具备适用性广、保密性高和灵活性强的特点。

The network technology,multimedia technology and communication technology has been widely used in all aspects of education.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 security,we presented a kind of security management for the teaching material by the watermarking based on chaos.We also presented the chaos-based authentication OPT technology and the real-time chaotic secure communication technology for online video teaching system.Experimental results show that the chaos technology applications in education resource protection have wide applicability,high security and flexibility features.
