Abstract
We propose a fast encryption method for MPEG video which encrypts the sign bits of DC coefficients and uses a random scan instead of zig-zag one. The proposed algorithm is a method which combines an encryption with MPEG video compression. Furthermore, it has short processing times for the encryption and provides sufficient security from the viewpoint of visibility and signal to noise ratio values. Thus the proposed method is suitable for the protection of the moving pictures with minimizing the overhead of MPEG video codec system. Also, we consider an authentication method appropriate for stream data such as MPEG video.
