摘　　要：提出一种针对H.264标准的新型视频加密算法,弥补了选择性加密压缩比变化及熵编码加密编码器不通用的问题。该算法将由密钥决定的一帧图像的细节与背景分别异或在原始图像帧的对应位置,生成视觉重叠图像以达到加密目的。实验结果表明,算法能够有效控制压缩率变化并可作为通用插件植入H.264编解码器中,适应于视频实时通信场合的需求。A new video encryption algorithm based on H.264 coding standard was proposed.In this algorithm,a frame image which is determined by the key XOR the original image both in details and background accordingly,to generate visual overlapping images and achieve the purpose of encryption.Experimental results demonstrate that the algorithm has very limited impact on the compact radio,and can be used as general plug-in in H.264 coder.The proposed algorithm is suitable for real-time video communication requirements.
