In this paper, we present a four-message protocol for initial authentication that supports subsequent authentication in two messages without contacting the authentication server or using synchronized clocks. This protocol has the property of using fewer messages to provide better security. Based on the protocol, a secure authentication system is built, which uses the master/ slave scheme to provide better reliability and reduce the load on an authentication server.
