H.264标准中基于感知加密算法的视频加密方案

摘要

To meet the requirement of multimedia video transmission"s safety and real-time .this paper provides a conclution based on video encryption schemes of the encryption algorithm.The solution sorts video data into VLC (Variable Length Code) and FLC (Fix-Length Code) ,only choose to reconstruction images FLC compared to encrypt the important element of the operation. The analysis and the simulation results show that the encryption scheme is not only high safety but also low cost system.%针对多媒体视频传输的安全性与实时性的要求,提出一种基于H.264感知加密算法的视频加密方案.该方案将视频数据分为VLC(Variable Length Code)和FLC(Fix-Length Code)两类,只选择FLC中对重构图像比较重要的元素进行加密操作.理论分析和仿真结果表明,该加密方案具有安全性高,低成本系统开销的特性.
