EFFECTIVE KEY GENERATION FOR MULTIMEDIA AND WEB APPLICATION

The Effective Key Generation for Multimedia and Web Application is used as the core component of many web and multimedia applications such as pay-TV, teleconferencing, real-time distribution of stock market price and etc. The main challenges for secure multicast are scalability, efficiency and authenticity. In this project, we propose a scalable, efficient, authenticated group key agreement scheme for large and dynamic multicast systems. The proposed key agreement scheme is identity-based which uses the bilinear map over the elliptic curves. Compared with the existing system, the proposed system provides group member authenticity without imposing extra mechanism. Furthermore, we give a scalability solution based on the subgroups, which has advantages over the existing schemes. Security analysis shows that our scheme satisfies both forward secrecy and backward secrecy
