An authentication and key distribution system for open network systems
Shiuhpyng Winston Shieh, Wen-Her Yang · ACM SIGOPS Operating Systems Review · 1996
In this paper, we present a four-message protocol for initial authentication that supports ubsequent authen-tication in two messages without contacting the au-thentication 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 eliability and reduce the load on an authentication server.
