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 paper demonstrates that the modification in kaman protocol can increase authorization. The authors 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.
