摘　　要：随着计算机技术和网络技术的发展,网络多媒体应用也随之扩展到了各行各业。但由于网络的开放性,使得网络上传输的多媒体内容很容易受到针对性攻击,同时,在不同应用场合,对于视频传输的安全性、实时性和计算复杂度均有不动的要求。提出了一种基于H.264/AVC的非对称视频加密方案,通过将视频数据分割后按重要性分类,采用AES和Salas20算法对分类数据进行不对称加密的方法,能够满足不同安全强度的应用需求。With the development of computer and network technology,video applications also extend to all trades and professions.However,due to the openness of the Internet,video contents are vulnerable to targeted attacks and there are different requirements for security,real-time video transmission and computational cost in different applications.In this paper,we propose an unequal video encryption scheme for H.264/AVC.According to the data importance,we classify the whole video data into different groups,then use AES and Salas20 algorithm to encrypt each groups separately.This scheme shall meet the application requirements in different security intensity levels.
