摘要
文章结合MPEG-2格式视频流的特点,研究MPEG-2格式视频流的加密方法。通过研究椭圆曲线加密算法和基于混沌理论加密算法对视频数据的影响,同时进行相应的实验验证和分析。提出了一种了基于混沌理论MPEG-2格式视频加密算法。
This paper research the digital eneryption of MPEG-2 video stream based on the characteristic of MPEG-2 video stream. The encryption method based on ECC and the new encryption method based on chaos theory are applied on the MPEG-2 system directly. We test the new encryption method based on chaos theory and get a better result than the other methods we have discussed.
