Lightweight Failover Authentication Mechanism for IoT-Based Fog Computing Environment

Fog computing as an extension to the cloud infrastructure has been invaluable in enhancing applicability of Internet Things (IoT) paradigm. IoT based systems magnify range and minimize latency applications. However, fog nodes are considered transient they offer authenticated services, when end device loses connectivity with a node, it must authenticate freshly secondary node. In this work, we present new security mechanism leverage initial authentication perform fast lightweight ensure smooth failover among nodes. The proposed scheme is secure presence current de-facto Canetti Krawczyk (CK)-adversary. We demonstrate detailed analysis using formal under broadly recognized Real-Or-Random (ROR) model, informal well through verification broadly-used Automated Validation Security Protocols Applications (AVISPA) software tool. A testbed experiment for measuring computational time different cryptographic primitives Multiprecision Integer Rational Arithmetic Cryptographic Library (MIRACL) done. Finally, comparative other related schemes, show how presented approach uniquely advantageous over schemes.
