A Scalable Video Encryption Algorithm for H.264/SVC

As the extension of H.264/AVC standard, Scalable Video Coding (SVC) has achieved significant improvements in coding efficiency and scalability. Most of the available video encryption algorithms are designed based on H.264/AVC standard. In this paper, the extensional technologies in SVC relative to H.264/AVC are analyzed. According to the new characteristics, a scalable video encryption algorithm is proposed for H.264/SVC. Some new features, such as motion prediction information of spatial scalability and key picture information of MGS (medium-grain quality scalability), are encrypted with three domains in hierarchical layers using different keys. Performance analysis of the new algorithm is reported and its strength against cryptanalysis attacks is discussed. Experimental results indicate that our scheme has adequate performance to allow for its use in real world applications.
