Abstract
Multimedia data is being used more widely in the field of Internet communication technology. Over wireless networks, extensive use of multimedia applications can easily be intercepted. The widespread use of multimedia data makes media content security and protection increasingly urgent and necessary. In order to fully protect or maintain security and privacy of multimedia data, it must be secured through encryption before transmission. Multimedia encryption is the core enabling technology that provides confidentiality and end-to-end security preventing unauthorized access of the information. In this paper, an encryption algorithm is proposed to achieve the desired integrity. Compressed video frames usingH.264 with multi-view video coding MVC are encrypted using a hybrid algorithm based on modified advanced encryption standard AES with 1D, and 2D chaotic maps. The encryption process replaces add round key and S-box operations of AES encryption by XOR operation and chaotic map generators on different blocks of input data frames. The results of our simulation using MATLAB show that the proposed algorithm is suitable for multimedia encryption applications.
