Secured selective encryption algorithm for MPEG-2 video

Rising popularity of internet technology has opened up many popular internet applications like Video on Demand, Internet TV, Video Conferencing, Telemedicine etc. But unwanted third party, the adversary can have access to the content if there is no security. Therefore, the security and privacy of the video content has become a challenging issue in the last decade. Many encryption algorithms have been proposed to meet the security requirements of the different applications. But, lack of application friendliness limits those algorithm form practical implementation. In this paper, we have proposed one selective video encryption algorithm to address the real-time security requirements. We propose one bits selection algorithm to select the higher intense bits to achieve higher visual degradation. In this paper, we have used AES encryption algorithm for encryption. This enhances the cryptographic security of the algorithm which will be well suited for real-time data transmission application.
