Abstract

Internet-of-Things (IoT) is an awaited technology in real-world applications to process daily tasks using intelligent techniques. The main process of data in IoT involves communication, integration, and coordination with other real-world applications. The security of transferred, stored, and processed data in IoT is not ensured in many constraints. Internet-enabled smart devices are widely used among populations for all types of applications, thus increasing the popularity of IoT among widely used server technologies. Smart grid is used in this article with IoT to manage large data. A smart grid is a collection of numerous users in the network with the fastest response time. This article aims to provide high authentication to the smart grid, which constitutes secure communication in cloud-based IoT. Many IoT devices are deployed openly in all places. This open-access is vulnerable toward cloning attacks. Authentication is a significant process that provides strength while attacking. The security of the cloud and IoT must be computationally high. A lightweight authentication using hashing technique is proposed considering the aforementioned condition. The main factor of the authentication involves physically unclonable functions, which are utilized in improving the performance of the authentication. The proposed approach is evaluated with the existing techniques. Results show that the performance of the proposed algorithm provides high robust security.
