In the context of today’s rapidly changing world, multimedia data have been used more and more widely in human being’s life. Large amounts of multimedia data have been produced and diffused in several fields. Thus, various encryption approaches for multimedia applications and services have been proposed in order to gratify different applications. Many video encryption algorithms combine encryption within the video coding algorithm to satisfy both video compression and encryption. In fact, the H.264 Advanced Video Coding (H.264/AVC) standard is one of the most frequently used formats for video compression. In this paper, we propose a novel selective encryption method that combines two encryption techniques and deals with the requirements of the real-time applications. The proposed scheme achieves video encryption using a chaos key generator and the AES (Advanced Encryption Standard) algorithm. To evaluate the proposed scenarios, we calculated the hardware performances and conducted five different security analyses.
