    摘要
  • 摘要: 在无线网络中,视频传输经常会引起严重的错误传播,以及安全传输问题.高效、安全、可靠的视频传输面临极大的挑战.作者针对H.264流媒体,采用数据分割技术对码流进行分割,增强视频传输的鲁棒性;并利用Logistic映射和Henon映射生成复合混沌序列,对码流进行选择性流加密,确保其安全性.实验结果表明,该机制在不降低其安全性的同时,具有较好的实时性,易于实现,适合应用在无线网络传输环境中.

     

    Abstract: In wireless networks,video transmission often causes serious error propagation and safe transport problems.It is great challenging for efficient,safe and reliable video transmission.Based on H.264 streaming media,this paper used data-partition technology to stream segmentation,which enhanced the robustness of stream transmission,and carried out selective encryption on the video sequence in the compound chaotic sequence generated by using Logistic mapping and Henon mapping.The experimental results showed that the mechanism was a good real-time performance and easy to implement,while without reducing its safety,so it was suitable for application in wireless networks.
