The reliable authentication of a communicating party and a network component is an essential factor to achieve the security in a computer network. The Kerberos Authentication Services has been the most successful solution which is widely used today but its requirement for synchronized clocks has been a serious limitation to use it. In this paper we presented an extended Kerberos method which avoids the synchronization requirement for a single-time ticket user. We modified the Kerberos protocol minimally by replacing the synchronization requirement with the challenge-response method.
