Moving objects encryption of high efficiency video coding (hevc) using aes algorithm

In recent time,the security of multimedia information has become a topic of great interest to researchers worldwide. one of the main concerns of multimedia security is content protection techniques which primarily involves encryption. in this paper,we discuss a new technique in encrypting moving objects in high efficiency video coding (hevc) media. due to high computational complexity requirements of video encryption,selective encryption for the moving objects in the contents of the video has been encrypted. vertical data of motion vector difference (mvd) has been selected to be encrypted using the aes algorithm. the result has shown that the scheme provides an adequate security level for the moving objects information while giving consideration to the trade-off between the computational complexity,the encryption reliability and video coding efficiency for a real- time application.
