Abstract

In open distributed environment several users accesses the network resources on server, server will allow only authenticated users to access these resources. So it has become of prime importance for nodes communicating over a non-secure network to prove their identity to one another in a secure manner.Various authentication protocols is used for the this purpose, Kerberos protocol is one of them. Several versions of the protocol exist. The aim of this paper is modeling and verification of the Inter Realm Authentication and User to User Authentication in Kerberos protocol through NuSMV model checker. It also demonstrate that when presence of intruder in the system, and make use of service, it will generate the counter example.
