A Pythagorean Tree based Key Generation Algorithm for Secure Group Communication in MANETs

چکیده
An efficient and secure group communication in Mobile Adhoc Network (MANETs) has brought attention to many security issues. In this paper, we propose Energy Efficient Dynamic Core based Multicast Routing Protocol to establish the path between the nodes that participate in group communication. During the routing process each node computes a Pythagorean Triple and constructs a Pythagorean Triple Tree (PTT) to generate a Contributory Key. Each node computes a pair of keys which will be exchanged among the nodes to compute group key for secure group communication. The rekeying operation is performed when the node join/leave the group. The proposed approach was analyzed on Computational cost, Group Formation, Percentage of Rekeying of nodes and Communicational cost with respect to Group Size. It reduces computational and communicational cost of the secure group communication when compared with other protocols.

In this paper, we first provide a spanning tree (ST)-based centralized group key agreement protocol for unbalanced mobile Ad Hoc networks (MANETs). Based on the centralized solution, a local spanning tree (LST)-based distributed protocol for general MANETs is subsequently presented. Both protocols follow the basic features of the HSK scheme: 1) H means that a hybrid approach, which is the combi...

It is essential to provide authentication on mobile nodes in group communication to ensure security and privacy. The nodes that are interested in participating in the group communication form Graphs (V, E). In this paper we authenticate the mobile nodes through transitive closure property of the graph in the routing phase of the On Demand Multicast Routing Protocol (ODMRP) that forms Transitive...
