Research on Video Encryption Algorithm of Air Unmanned Information Platform
Zhang Hao-quan · Microcomputer Information · 2008
Video encryption is a suitable method to protect video data, especially in the area of military communication. Through analysising the MPEG encryption algorithms that are present now, we propose a video encryption algorithm which is suitable to the air unmanned information platform. This algorithm only encrypts DC code, signs of AC coefficients and signs of motion vectors MV. It encrypts little data and has higher security.
