Paper Abstract

With the emergence of new distributed multimedia applications upon secure group communication, Security becomes more important increasingly. Now most investigations about multicast security focus on key management problem. In this paper, an improved version of CBT is proposed for data communication and key management and named as Dynamic CBT(D-CBT). This approach accepts the advantages of Iolus and CBT approaches, its main characteristic is that D-CBT changes dynamically with group member join/removal frequently when cumulating influence of dynamic membership reaches certain threshold so that the bandwidth/cost of multicast is as least as possible, D-CBT is also very close to realistic application case. Performance analysis will be conducted compared with other methods.
