Abstract: This paper introduces a three-factor authentication project for the thin client/server system, which adds a device authentication factor on the traditional double-factor authentication. The realization method of the authentication protocol is also given, followed by a rough valuation on its practicability and security. Practical applications prove this authentication project is feasible.
