Abstract

In this paper, we propose an encryption algorithm to protect scalable video coding (SVC) bitstream and a method for conditional access control to consume the encrypted SVC bitstream. To design an encryption algorithm, we analyzed the encryption requirements to support scalability function in the scalable video and proposed an effective encryption method developed in the network abstraction layer (NAL). In addition, conditional access control scheme and key management scheme are proposed to consume the SVC bitstream protected with proposed method. Experiments were performed to verify the proposed method and results showed that proposed algorithms could provide an effective access control of scalable video as well as support a video encryption with scalability function.
