“…Physically unclonable functions or features (PUFs) leverage random manufacturing variations and nonlinearities to derive an immutable device identifier [125][126][127][128][129] and can be used for detecting and avoiding counterfeits. We distinguish PUFs from fingerprints in that PUFs are intentionally added to a circuit to leverage the randomness in a manufacturing process to engineer a random, but repeatable, behavior.…”

We introduce and explore the early implications of an innovative technological development known as Physically Unclonable Functions (PUFs). We review the main technological developments of product and asset tracking in the supply chain management field ranging from barcode, radio frequency identification (RFID) tags and the Internet of Things (IoTs). We then introduce the PUF: its definition, technical attributes and why it brings unique advantages to product tracking. Several use cases are explored demonstrating how PUFs may add value to supply chains, particularly when combined with emerging technologies such as blockchain. We conclude by discussing potential issues for managers in trying to adopt PUF technology and its limitations.

“…The design of a secure communication scheme for the resource constraint IoT devices is the main challenge of the researchers 22,23 . Moreover, remote authentication 24‐33 is needed to set up efficient and secure communication between the user and the remote server. In order to deal with security, confidentiality, and access right only authorized user can access resources related to the cloud server 34‐37 .…”

The Internet of Things adapted by the industries, known as Industrial Internet of Things (IIoT), increases the production rate by reducing the risk factor. The wireless devices deployed in the open places are always susceptible to various attacks including cloning and physical attacks. Thus security of IIoT devices becomes the primary concern of these days. The resource constraint IIoT devices demand light weight security schemes to authenticate communicating devices and protect the privacy of industrial data. In this article, an authentication scheme with low computation and communication cost has been proposed using multiple factors, namely smart card, password, physical unclonable function (PUF), and fuzzy extractor. PUF helps in preventing the cloning of smart card and generates unique challenge‐response pairs to authenticate the smart devices. The environmental noise, produced by the operation of PUF, is extracted by the use of fuzzy extractor. Real‐or‐Random (ROR) model and Burrows‐Abadi‐Needham (BAN) logic has been used for formal security analysis of the proposed scheme, which is resilience against replay attack, man‐in‐the‐middle attack, masquerading, forgery and impersonation attacks, camouflage attack and offline password guessing attack. The performance evaluation has been done using Raspberry Pi, lunchbox, and a laptop. The simulation results show that the proposed scheme outperforms the existing methodologies in terms of end‐to‐end delay, throughput, packet loss, computation cost, and communication cost.
