A simple PUF-based authentication circuit is proposed that will lower the entry barrier for counterfeit countermeasures by COTs manufacturers of integrated circuits. The on-chip fingerprint circuit does not require additional die area, I/O pins, or a separate read-out circuit. This approach to assuring integrity in the semiconductor supply chain will result in negative financial incentives for counterfeiters. An 80 bit authentication circuit which includes a 16 bit frame header has been designed in a UMC 65nm process with an area estimate of 0.01 mm2.

Hybrid PUF for Counterfeit Mitigation
A subthreshold hybrid PUF-embedded authentication circuit is proposed to mitigate the financial incentives that drive the counterfeit community and to encourage the COTS manufacturers to use authentication for system identification in their parts. The proposed hybrid PUF with cross-coupled inverters and a delay-based PUF strategy has sufficient entropy for authentication and a reduced number of transistors per bit. The area efficient fingerprint circuit does not require additional die area, pins, or power overhead. The performance of the primary circuit is unaffected by the fingerprint circuit. The hybrid circuit designed in a 65 nm CMOS process is discussed.

A simple and compact authentication circuit based on a 4T bit cell is proposed for counterfeit detection and avoidance. The PUF-based authentication circuit has been designed to reduce or eliminate the reluctance of COTs manufacturers to include onchip fingerprints by not requiring additional die area, I/O pins, or read-out circuits and by using a deep-sleep mode during normal circuit operation so that it does not interfere with operation of the main IC.more » « less

This article presents a novel hardware-assisted distributed ledger-based solution for simultaneous device and data security in smart healthcare. This article presents a novel architecture that integrates PUF, blockchain, and Tangle for Security-by-Design (SbD) of healthcare cyber–physical systems (H-CPSs). Healthcare systems around the world have undergone massive technological transformation and have seen growing adoption with the advancement of Internet-of-Medical Things (IoMT). The technological transformation of healthcare systems to telemedicine, e-health, connected health, and remote health is being made possible with the sophisticated integration of IoMT with machine learning, big data, artificial intelligence (AI), and other technologies. As healthcare systems are becoming more accessible and advanced, security and privacy have become pivotal for the smooth integration and functioning of various systems in H-CPSs. In this work, we present a novel approach that integrates PUF with IOTA Tangle and blockchain and works by storing the PUF keys of a patient’s Body Area Network (BAN) inside blockchain to access, store, and share globally. Each patient has a network of smart wearables and a gateway to obtain the physiological sensor data securely. To facilitate communication among various stakeholders in healthcare systems, IOTA Tangle’s Masked Authentication Messaging (MAM) communication protocol has been used, which securely enables patients to communicate, share, and store data on Tangle. The MAM channel works in the restricted mode in the proposed architecture, which can be accessed using the patient’s gateway PUF key. Furthermore, the successful verification of PUF enables patients to securely send and share physiological sensor data from various wearable and implantable medical devices embedded with PUF. Finally, healthcare system entities like physicians, hospital admin networks, and remote monitoring systems can securely establish communication with patients using MAM and retrieve the patient’s BAN PUF keys from the blockchain securely. Our experimental analysis shows that the proposed approach successfully integrates three security primitives, PUF, blockchain, and Tangle, providing decentralized access control and security in H-CPS with minimal energy requirements, data storage, and response time.more » « less

Tag cloning and spoofing pose great challenges to RFID applications. This paper presents the design and evaluation of RCID, a novel system to fingerprint RFID tags based on the unique reflection coefficient of each tag circuit. Based on a novel OFDM-based fingerprint collector, our system can quickly acquire and verify each tag’s RCID fingerprint which are independent of the RFID reader and measurement environment. Our system applies to COTS RFID tags and readers after a firmware update at the reader. Extensive prototyped experiments on 600 tags confirm that RCID is highly secure with the authentication accuracy up to 97.15% and the median authentication error rate equal to 1.49%. RCID is also highly usable because it only takes about 8 s to enroll a tag and 2 ms to verify an RCID fingerprint with a fully connected multi-class neural network. Finally, empirical studies demonstrate that the entropy of an RCID fingerprint is about 202 bits over a bandwidth of 20 MHz in contrast to the best prior result of 17 bits, thus offering strong theoretical resilience to RFID cloning and spoofing.more » « less
