Authenticated ID-based Key Exchange and remote log-in with simple token and PIN number

Mike Scott

Abstract: Authenticated Key exchange algorithms tend to be either token-based or password based. Token-based schemes are often based on expensive (and irreplaceable) smart-card tokens, while password-only schemes require that a unique password is shared with every correspondent. The magnetic strip swipe card and associated PIN number is a familiar and convenient format that motivates a combined approach. Finally we suggest an extension of the scheme for use in a client-server scenario.
