Modification in the Kerberos Assisted Authentication in Mobile Ad-hoc Networks to Prevent Black Hole Attack

Abstract

MANET is the self-configuring type of network in which the mobile nodes can leave or join the network when they want. MANET is decentralized type of network, no central controller is present. Due to their unique features mobile ad hoc networks can be deployed anywhere round the clock. This posed the remedial venture to large number of attacks like replay attack, fabrication, eavesdropping etc Kaman provides secure solution to the problem of secure channel establishment, secure exchange of session keys and prevention of nodes identity forgery. In this paper, we reviewed the Kaman; Kerberos assisted Authentication in Mobile Ad hoc Network and added the concept of timers in KAMAN to solve the problem of black hole attack that aroused when Kaman protocol is embedded into large network AODV, on-demand routing protocol had been used to select secure shortest path between the nodes.
