强实时性流媒体数据保密方案设计

Strong Real Time Streaming Media Data Security Scheme Design

由于网络视频服务的广泛应用,强实时性流媒体数据的安全性成为现今的研究热点。本文分别从保证视频数据本身的安全性和保证传输过程的安全性出发,提出了一套完整合理的强实时性流媒体数据保密方案。首先基于利用Logistic映射和Chebyshev映射形成的交叉混沌序列提出了MPEG视频流的选择加密算法,并给出实验结果和相关性能分析。然后选择合适的网络传输协议,并对于数据包丢失所引起的解密错误扩散问题提出了相应的解决方法。最后给出了完整方案设计图。

due to the wide application of network video service, the security of the strong real-time streaming media data has become a hot research topic. In this paper, we propose a set of complete and reasonable scheme for the security of video data. Based on the cross chaotic sequences formed by Logistic mapping and Chebyshev mapping, a MPEG video stream is proposed, and the encryption algorithm is proposed, and the experimental results are also given. Then select the appropriate network transport protocols, and propose the corresponding solution to the problem of the loss of data packets. Finally, a complete scheme is given.
