Abstract—Security is an important issue for any type of networks, especially for wireless ad-hoc networks. Kerberos tickets used in KAMAN authentication scheme can be captured over the network are prone to replay attacks. The research work described in this document demonstrates that the modification in KAMAN protocol can increase authorization. We are proposed that all of contents are encapsulated in an encrypted packet. So the replay attacks become impossible. Moreover, in the proposed scheme there is no burden on the server and the client to undertake the modified KAMAN process. We also simulate describe architecture and verified that propose methods can reduce the chances of reply attack in MANET using KAMAN as authentication protocol.
Index Terms—KAMAN, reply attacks, security in MANET, confidentiality, non-repudiation.
