“…As mentioned in the introduction of this paper, analog-based PUF designs benefit from relatively simple circuit designs, which make them suitable for the integration into IoT devices that are mostly bound to hard requirements such as being small-sized, low-cost and having limited resources. Various analog-based PUF designs have been reported earlier by other working groups [22][23][24][25][26]. In the following, we provide a closer look at other analog-based PUFs, similar to our system.…”

“…The most commonly used classes divide into bi-stable or delay-based PUFs [14][15][16][17][18][19][20][21]. Other works also target the class of analog-based PUF designs [22][23][24][25][26]. A further classification relies on the complexity of the challenge-response mechanism, more particularly on the number of challenge-response pairs (CRPs).…”

“…The TV-PUF [23] uses two parallel blocks with cascaded pass-transistors. Cascading helps to accumulate the impact of V th variation per pass-transistor, which is subtracted from V DD over the amount of pass-transistor stages.…”

Internet of Things (IoT) enabled devices have become more and more pervasive in our everyday lives. Examples include wearables transmitting and processing personal data and smart labels interacting with customers. Due to the sensitive data involved, these devices need to be protected against attackers. In this context, hardware-based security primitives such as Physical Unclonable Functions (PUFs) provide a powerful solution to secure interconnected devices. The main benefit of PUFs, in combination with traditional cryptographic methods, is that security keys are derived from the random intrinsic variations of the underlying core circuit. In this work, we present a holistic analog-based PUF evaluation platform, enabling direct access to a scalable design that can be customized to fit the application requirements in terms of the number of required keys and bit width. The proposed platform covers the full software and hardware implementations and allows for tracing the PUF response generation from the digital level back to the internal analog voltages that are directly involved in the response generation procedure. Our analysis is based on 30 fabricated PUF cores that we evaluated in terms of PUF security metrics and bit errors for various temperatures and biases. With an average reliability of 99.20% and a uniqueness of 48.84%, the proposed system shows values close to ideal.

“…In the next step, silicon-based PUFs (Si-PUFs), leveraging intrinsic manufacturinginduced variations of integrated circuits (ICs), were studied and present a well-established PUF implementation 5,[12][13][14]17,18 . Si-PUFs can be further classified as bi-stable [19][20][21] , delay-based 22 , or analog PUFs 23,24 , depending on the underlying variation source, such as dopants, defects, and geometrical device dimensions. Furthermore, Si-PUFs often suffer from reduced entropy 25 , compared with additive manufacturing techniques.…”

Modern society is striving for digital connectivity that demands information security. As an emerging technology, printed electronics is a key enabler for novel device types with free form factors, customizability, and the potential for large-area fabrication while being seamlessly integrated into our everyday environment. At present, information security is mainly based on software algorithms that use pseudo random numbers. In this regard, hardware-intrinsic security primitives, such as physical unclonable functions, are very promising to provide inherent security features comparable to biometrical data. Device-specific, random intrinsic variations are exploited to generate unique secure identifiers. Here, we introduce a hybrid physical unclonable function, combining silicon and printed electronics technologies, based on metal oxide thin film devices. Our system exploits the inherent randomness of printed materials due to surface roughness, film morphology and the resulting electrical characteristics. The security primitive provides high intrinsic variation, is non-volatile, scalable and exhibits nearly ideal uniqueness.
