An Overview of Encryption Scheme for Digital Video

In this paper,the issues about digital video encryption algorithms include the essential cryptogrammic knowledge and techniques, the open problems and the most important schemes, research hotspots and their progresses, and prospects are summarized and overviewed. Through the analysis of current encryption schemes for encoded digital video, it is pointed out that an alternative encryption scheme based on characteristics of source data format for compression encoding of digital video is the future trend of video encryption.
