基于流媒体相关的视频安全组播协议(MSMP)研究

随着无线网络的快速发展和Internet中流媒体视频的巨大成功,无线网络中的视频服务有望在不久的将来得到大规模部署,无线网络上的实时流媒体传输技术已成为研究热点,而其中视频安全组播协议是一个关键问题。但是,由于无线网络中有限的带宽和有限的存储空间,外部的攻击与自适应机制带来的安全性问题在无线流媒体视频中是不可避免的。一个精心设计的密钥管理算法不仅可以明显地提高流媒体视频的性能,还能够保证可靠的数据嵌入以及实时视频应用提供安全支持。如何设计一个高效的密钥管理算法,是当前流媒体视频应用中一个备受关注的问题。针对无线视频应用,针对一个处于开放和不安全的网络环境中的自适应视频应用的密钥管理算法进行了研究,并进行了算法评价。

A Research of MSMP based on Streaming Media

With the rapid development of wireless networks and Internet streaming media video success,a wireless network video service is expected in the near future are deployed,the wireless network real-time streaming media transmission technology has become a research hotspot,and the video security multicast protocol is a key problem.However,due to the wireless network in the limited bandwidth and limited storage space,the exterior attack and adaptive mechanisms of the security issues in wireless video streaming media is inevitable.A well-designed key management algorithm can significantly improve the performance of streaming video,but also ensures the reliable data is embedded and realtime video applications to provide safety support.How to design an efficient key management algorithm,is the current streaming video applications a concerned problem.Aiming at the wireless video applications,for an open and insecure network environment adaptive video application key management algorithm are studied,and the algorithm evaluation.
