A secure lightweight anonymous elliptic curve cryptography‐based authentication and key agreement scheme for fog assisted‐Internet of Things enabled networks

Abstract

Summary The fog assisted‐Internet of Things (IoT) enabled network has been a novel topic in recent years. With the rapid development of the IoT, it is imperative to accomplish security in the fog computing environment. The surface for cryptographic attacks is expanded since the fog node can analyze, store, and process data between cloud and IoT device. This article proposes elliptic curve cryptography (ECC) based mutual authentication and key agreement scheme to support secure communication between device and fog server. In this work, we have formally analyzed the proposed scheme using the most widely accepted automated validation of Internet security protocols and application (AVISPA) tool. The informal security analysis of the proposed scheme shows that the proposed method is robust against several attacks. The performance analysis has been evaluated in terms of computation and storage overhead. The security and performance analysis with theoretical proof indicates that proposed scheme attains better security than related schemes.
