Recently, multimedia security is becoming more important with the continuous increase in transmission of digital content and also in the digital communications. However, special and reliable security is needed in many digital applications (such as video conferencing ). The classical techniques for data security are not appropriate for the current multimedia usage like images and videos with very large file sizes. As a result, we need to develop new security protocols or adapt the available security protocols to be applicable for securing the multimedia applications. In spite of extensive research in multimedia security, encryption of MPEG video streaming using AES has not been studied. In this paper, the performance of AES in encrypting MPEG video is considered. The performance of AES is compared to two symmetric encryption techniques. Three data types (text, audio and video) are used to test the effectiveness of encrypting MPEG using AES.
