Abstract

Cloud computing is a state-of-the-art technology using which a resource starved client can access various services from a remote cloud server. Accessing such remote services requires that the client and server authenticate each other and come to agree on a common session key in secure manner. Most of the recent mutual authentication and key agreement protocols use two and three factor smart card and biometric based techniques. However, due to the consequent increase in cost of resources and added operational complexity, one factor authentication schemes are still popular. In this paper a lightweight Elliptic Curve Cryptography based one factor three way mutual authentication and key negotiation scheme between a lightweight client and server is proposed with proven safety.
