چکیده انگلیسی
This paper proposes a new and secure video encryption method based on chaotic maps in DCT domain, which is quite in keeping with the common ideas and the frequent practices of video encryption. We select the I-frames of the video sequence as encryption objects. First, we introduce two coupling chaotic maps to scramble the DCT coefficients of every original I-frame, and receive the scrambled I-frame. Second, we encrypt the DCT coefficients of the scrambled I-frame using another chaotic map. In the whole process, we use three chaotic maps and five keys; the I-frame is encrypted twice. Finally, we performed several tests and the experimental results have proved our method to be secure and efficient.
