高级视频编码是最近宣布并广泛使用的，尽管相应的保护手段还没有完全开发出来。本文提出了一种基于高级视频编码的选择性加密方案。在AVC编码过程中，对帧内预测模式、残差数据、帧间预测模式和运动矢量等敏感数据进行部分加密。该加密方案具有抗暴力攻击、替换攻击和已知明文攻击的安全性，以较低的成本将加密过程和压缩过程相结合，并通过一些直接操作(如显示、寻时、复制、剪切等)保持文件格式不变。支持。这些特性使其适用于安全的视频传输。
Advanced Video Coding is recently announced and widely used, although the according protection means have not been developed thoroughly. In this paper, a selective encryption scheme is constructed on Advanced Video Coding. During AVC encoding, such sensitive data as intra-prediction mode, residue data, inter-prediction mode and motion vector are partially encrypted. This encryption scheme keeps secure against brute-force attack, replacement attack or known-plaintext attack, combines encryption process with compression process with low cost, and keeps the file format unchanged with some direct operations (such as displaying, time seeking, copying, cutting, etc.) supported. These properties make it suitable for secure video transmission.
