Abstract

We propose a new key distribution scheme for multimedia multicast by exploiting the characteristics of multimedia signals. First, a basic rekeying message construction is presented which can be used to distribute rekeying material to a group of users using number theoretic techniques. We then map the basic rekeying form to a logical tree structure to achieve logarithmic scalability and discuss several key updating strategies. Furthermore, we present a general key distribution scheme using data embedding for multimedia multicast. The performance and system feasibility of the proposed scheme is also analyzed. We also extend the key management scheme for multilayer multimedia applications in heterogeneous networks where group members have different quality requirements.
