Fault tolerant analysis of secure multicast models

Recently, fault tolerant secure multicast services have received much attention among researchers. The fundamental challenge revolves around developing a self-stabilized, fault tolerant secure multicast model. In this paper, the fault tolerant nature of different secure multicast models are evaluated and analyzed. Also the recently proposed LeaSel model [R. E. Blessing and V. R. Uthariaraj, Dec 2002] is implemented, experimentally tested and analyzed to determine its fault tolerance behavior. The results show that for different numbers of members in the group, the LeaSel model exhibits self-stabilization property and proves to be absolutely fault tolerant.
