A Lightweight Trust Based Secure Authentication Mechanism for IoT Devices

Abstract

Abstract The Internet of Things, which is in the next phase of communication, is quickly overtaking all other technologies. IoT enables seamless data exchange, interaction, and communication between various physical objects. IoT brings automation and intelligence to a variety of industries and fields, including agriculture, transportation, industry, and health. Improving user efficiency and comfort is the goal of IoT applications. The security of internet-connected devices has recently become more important because of global cyber-attacks. Authentication is one of the most important network security principles, whether for small networks like local servers or large networks like central cloud servers. For IoT applications, several solutions have also been put forth, but they are not at all efficient and as well secure. In this paper, we have proposed a trust-based authentication method, which is not only lightweight but as well is secure. For verification of the security of the protocol AVISPA tool has been used in various modes.
