This paper proposes the use of Cellular Non-Linear Networks (CNNs) as physical uncloneable functions (PUFs). We argue that analog circuits o®er higher security than existing digital PUFs and that the CNN paradigm allows us to build large, unclonable, and scalable analog PUFs, which still show a stable and repeatable input output behavior. CNNs are dynamical arrays of locally-interconected cells, with a cell dynamics that depends upon the interconnection strengths to their neighbors. They…

Hybrid silicon CMOS-carbon nanotube physically unclonable functions

Physically unclonable functions (PUFs) are used to uniquely identify electronic devices. Here, we introduce a hybrid silicon CMOS-nanotube PUF circuit that uses the variations of nanotube transistors

REALIZATION AND ANALYSIS OF HIGH PERFORMANCE PHYSICAL UNCLONABLE FUNCTIONS BASED ON RING OSCILLATORS

Towards Electrical, Integrated Implementations of SIMPL Systems

This paper discusses strategies for the electrical, integrated implementation of a novel security tool termed SIMPL system, and proposes two potential candidates: SIMPL systems derived from special SRAM-architectures (so-called “skew designs” of SRAM cells), and implementations based on analog computing arrays called Cellular Non-Linear Networks (CNNs).

Automated Design, Implementation, and Evaluation of Arbiter-based PUF on FPGA using Programmable Delay Lines

A high resolution programmable delay logic (PDL) that is implemented by harnessing the FPGA lookup-table (LUT) internal structure allows automatic fine tuning of delays that can mitigate the timing skews caused by asymmetries in interconnect routing and systematic variations.

FPGA PUF using programmable delay lines

A high resolution programmable delay logic (PDL) implemented by lookup table (LUT) internal structure is introduced, and fine tuning is performed to cancel out delay skews caused by asymmetries in routing and systematic variations.

Challenges and Opportunities in Analog and Mixed Signal (AMS) Integrated Circuit (IC) Security

The challenges and limitations associated with AMS IC security research are described focusing on three major sections: AMS-enabled security, counterfeiting, and AMS hardware Trojans and a vision for AMS security research is expressed.

It is shown that specially designed circuits-which are possible to simulate but computationally outperform any feasible digital and hardware-assisted emulation-can be used to remotely and securely identify their owner and serve as a basis for various cryptographic protocols.

A PUF taxonomy

By carefully considering the physical mechanisms underpinning the operation of different PUFs, this review is able to form relationships between PUF technologies that previously had not been linked and look toward novel forms of PUF using physical principles that have yet to be exploited.

SpyHammer: Using RowHammer to Remotely Spy on Temperature

This work proposes a new RowHammer attack, called SpyHammer, that spies on the temperature of critical systems such as industrial production lines, vehicles, and medical systems.

Security and Privacy of PUF-Based RFID Systems

The need to use formal models in the study of the security and privacy of (PUF-based) RFID schemes is emphasized and the tag corruption oracle is broadly discussed and some aspects that can lead to schemes without security or privacy are highlighted.

It is proved that a CNN in which the parameters of all cells can be separately controlled is the analog correspondent of a two-dimensional Ising-type (Edwards-Anderson) spin-glass system, and it is shown that one single operation (template) always yields a local minimum of thespin-glass energy function.

It is shown that instead of relying on number theory, the mesoscopic physics of coherent transport through a disordered medium can be used to allocate and authenticate unique identifiers by physically reducing the medium's microstructure to a fixed-length string of binary digits.

Experiments show that the technique to reliably and securely identify individual integrated circuits (ICs) based on the precise measurement of circuit delays and a simple challenge–response protocol is viable, but that current implementations could require some strengthening before it can be considered as secure.
