MPEG-2 and ECC Security in DCT Domain

摘要

In this paper we give a new and robustness way to use the Elliptic Curve Cryptography for the security of a compressed MPEG-2 video. We encrypt the DC coefficient of the Index frame of the video, this allow our method to be faster than the other encryption scheme. We performed several tests and the experimental results have proved our method to be secure and efficient.
