摘要

分析和总结了用于新一代视频编码标准H.264/AVC加密的候选域

在此基础上提出了一种新的基于CABAC(基于上下文的自适应二进制算术编码)的数字视频加密方案

并给出了2种安全加密操作:RCME(规则编码模式加密)和BCME(旁路编码模式加密)实现了残差系数码字、运动矢量差码字和帧内预测模式的加密保护。实验结果表明

该方案具有较好的安全性、编码效率和误码顽健性。

Abstract

Several candidate domains were analyzed and summarized to apply encryption to the latest video coding standard H.264/AVC

and a novel digital video encryption scheme based on CABAC（context-based adaptive binary arithmetic coding） was proposed.During the CABAC encoding

two kinds of secure encryption operations including RCME（regular coding mode encryption） and BCME（bypass coding mode encryption） were utilized

in order to encrypt residual coefficient codeword

motion vector difference codeword and intra-prediction mode

respectively.The experimental results show that the scheme has significant advantages on security

coding efficiency

and errors robustness.
