Enhancing Security in Wireless Ad-Hoc Network Using ZKP

Abstract

Communication in network is based on client server model where an infrastructure is required between two clients or mobile to communicate with each other even though they are closed to each other. In earlier human communication model, two people those are physically closed to each other can talk directly without any server. In spontaneous network there is no server or any infrastructure between nodes to communicate, anybody those who wants to communicate can join, communicate and leave the network without any central server. Authentication in Wireless ad-hoc Network is difficult and challenging because of its frequent topology changes. Due to the mobility of nodes the connection may be loss. When the connectionless node wants to rejoin into the network node re-authentication will be needed. A secure self configured protocol is required for user authentication, validation and data transfer. Zero knowledge protocol is a secure self-authenticated protocol. Secured protocol uses a hybrid symmetric/asymmetric key encryption scheme for user authentication and to exchange data. ZKP is used to re-authenticate and share the secure services without any infrastructure. Central authority based authentication schemes have been proposed and with every movement of a node outside the network demands re-authentication of the nodes by the central authority before the node rejoins the network. ZKP reduces the dependences on the Central authority for re-authentication thereby avoiding the attacks that are possible during re-authentication and service sharing.
