Computation-and communication-efficient three-party encrypted key exchange protocols

Abstract

This paper proposes computation-and communication-efficient three-party encrypted key exchange (CC3EKE) protocols to minimize the complexity of computational and communicational costs among all users and fit three-party communication environments. Compare with related 3EKE protocols, the proposed CC3EKE protocols have enhanced computational and communicational efficiency. As a result, the proposed protocols are extremely suitable for use in various applications over distributed three-party network environments such as the Internet and the mobile e-commerce.
