为保证网络信息传输的安全性,提出一种视频图像加密方法。该方法引入混沌系统中的Logistic映射和
Baker映射,结合H·264视频压缩编码特点,利用Baker映射对DCT (Discrete Cosine Transform)变换量化后
的块进行位置置乱,
-In order to ensure the safety of information transmission network, and a video image encryption method. This method is the introduction of chaotic systems in Logistic mapping and Baker mapping, combined with H 264 video compression coding features, the use of Baker mapping of DCT (Discrete Cosine Transform) transform to quantify the location of block after scrambling,
