Securing Group Communication in Partially Distributed Systems
2012
IOSR Journal of Computer Engineering
This paper deals with symmetric key exchange in partially distributed systems. Unlike the traditional distributed approaches for key exchange utilized when we have a centralized KDC (Key Distribution Center), which is a trusted server responsible for key exchange between the users involved in group communication or a KDC for each node, we divide the group of nodes in regions with each having its own KDC. Each user can communicate securely with members of its own region as well as with those
