Implementing Secure Group Communications using Key Graphs
Ch. Aswani Kumar, R. Poornima Lakshmi, M. Preethi · Defence Science Journal · 2007
While the technical issues of securing unicast communications for client-server computing are fairly well-understood, the technical issues of securing group communications are not. The existing approach to improve the scalability is to decompose a large group of clients into many subgroups and employ a hierarchy of group security agents. In this paper, the secure group communications using key graphs and the implementation of a different hierarchical approach to improve the scalability and secure group communication using key graphs has been presented.
