Efficient Encryption of Intra and Inter Frames in MPEG Video

The growth in multimedia based Internet applications can be seen in the quantity of growth in video telephony, video on demand, media server etc. With the current cyber threats, sensitive video need to be protected before transmission. Streaming video applications requires high security as well as high computational performance. The need for video data protection is on rise hence encryption of video is imperative. In highly sensitive videos such as military applications, confidential video broadcasting where every part of the video is important it is required Intra and Inter frames need to be encrypted. A new video encryption scheme is proposed for sensitive applications. In this paper the objective is to analyze a secure and computational feasible video encryption algorithm for MPEG video, to improve the security of existing algorithm by combining encryption in Intra and Inter frames and to test the algorithm against the common attacks.
