| 摘 要： | 文章针对传统的加密算法难以满足数据量大、实时性要求高的数字视频的加密需要的问题,设计了一种基于混沌置乱的视频实时加密方法.该方法先计算出视频图像的特征值,再通过该特征值生成不同的混沌序列,然后利用这些不同的混沌序列实现对视频的运动矢量与QDCT块置乱.该方法具有加密实时性好,对视频输出速率影响小的特点.

| Abstract: | Aiming at the problem that the traditional encryption methods are difficult to satisfy the need for encryption of digital video which has large volume of data and requires high real-time,a real-time video encryption method based on chaotic scrambling is designed.This method first calculates the feature code of the video image,and generated different logistic chaotic sequences by it.Then,the different chaotic sequences are utilized to achieve the scrambling of motion vector and QDCT block.The encryption meth... |
