IoT Security in Supply Chain Using Blockchain
N Anita., M. Vijayalakshmi · 2021
The Internet of Things (IoT) has grown rapidly over the last decade as an emerging technology, offering various Internet-enabled devices to communicate in different contexts. With an ever-increasing time frame of the digital world, traceability and authentication have gained enormous significance. In general, a trusted third party is used to authenticate users, devices, or services in an IoT environment. However, in such situations, this centralized third party will become the focus of cyberattacks might not be the best solution. In this paper, a new authentication algorithm has been proposed to prevent malicious IoT devices. We address the traceability and authentication issues in IoT devices. This paper presents the concept of a blockchain that integrates Physical Unclonable Functions (PUFs) to solve security issues, malicious activities, latency, and energy consumption challenges. The results show that the proposed solution outperforms existing solutions with less computational overhead. Similarly, the possibility of an attack is decreased compared to the current system. Throughput is enhanced by 20% over the present system, while latency is decreased by 25% over the previous technique. As a consequence, the likelihood of an attack is decreased by 30% compared to the existing technique.
