This article proposes an efficient, less communication rounds, three-party encrypted key
exchange protocol to achieve the authentication requirement. The protocol is provided with
(1) no asymmetric encryption algorithm which is adopted to reduce the costs (such as any
public-key infrastructure); (2) using pre-shared key to prevent adversaries that masquerade
as legal users after guessing attacks; (3) avoiding the variant man-in-the-middle attacks on
Diffie-Hellman based protocols; (4) achieving mutual authentication. With these four
features, the proposed protocol is suitable for being applied for establishing secure channels
between two clients, which are supported with the same trusted server.
