Abstract: Media authentication is becoming an increasingly important issue in wireless transmission. Authenticated media content is required to be transcoded at intermediate to accommodate heterogeneous applications. In this paper, an efficient stream authentication approach is proposed for scalable lossy media streams. At first, we describe a joint coding and stream authentication (JCSA) media transmission framework for flexible and secure transcoding. After that, we propose a generalized quality-optimized stream authentication (QOSA) model to achieve optimal end-to-end quality and minimize the authentication overhead. Furthermore, an implementation on the consultative committee for space data systems image data compression (CCSDS IDC) coder is realized by using graph-based and error-correction coding based (ECC-based) authentication. Experimental results demonstrate that the proposed scheme is able to provide high packet-loss robustness at the cost of a very low overhead. © 2012 IEEE.
