| 摘 要： | 通过分析H.264中灵活宏块排序FMO(Flexible Macroblock Ordering)技术的特点和NALU(Network Abstract Layer Unit)语法元素的参数,利用编码过程中的FMO机制对图像分片后的宏块进行置乱,采用流密码对码流的网络抽取层单元NALU中的重要参数快速加密,提出一种基于...

| Abstract: | By analysing H.264 flexible macro-block ordering technology characteristics and NALU syntax element parameters,depending on encoding process FSO mechanism to scramble macro-blocks of image slices,exploiting stream cipher for network abstraction layer(an important NALU parameter) rapid encryption,the thesis proposes an FMO and NAL-based video encryption scheme.Experiment results and performance analysis show that compared with video encryption algorithm[9],the proposed scheme not only keeps FMO characteristi... |
