Proposal and Properties of Ring Oscillator-Based PUF on FPGA

JOURNAL OF circuits systems AND COMPUTERS 2016年第3期25卷 1640016-1640016页

作者： Kodytek, Filip Lorencz, Robert Czech Tech Univ Dept Comp Syst Thakurova 9 Prague 16000 Czech Republic

this paper deals with design of physical unclonable functions (PUFs) based on field-programmable gate array (FPGA). the goal was to propose a cheap, efficient and secure device identification or even a cryptographic key generation based on PUFs. therefore, a design of a ring oscillator (RO)-based PUF producing more output bits from each RO pair is presented. 24 Digilent Basys 2 FPGA boards (Spartan-3E) and 6 Digilent Nexys 3 FPGA boards (Spartan-6) were tested and statistically evaluated indicating suitability of the proposed design for device identification. A stable PUF output is required for generating cryptographic keys. As post-processing technique to further improve the efficiency of this PUF design, we used Gray code on the obtained bits from RO pairs. Ultimately, the PUF design is combined with error correction code and together with Gray code is able to generate cryptographic keys of sufficient length.

Hardware Trojan Horses (Hth) are a serious threat to semiconductor industry with significant economic impact. However, most of the research in Hth focuses on detection. We propose the concept of "encoded circuit", as a technique to protect Hth insertion. Encoded circuit is based on the theory of codes. It encodes the internal state with a chosen code of security parameter d, such that knowledge of less than d bits of the encoded state reveals no information about the actual state. this parameter stems from a similar notion introduced by Ishai, Sahai and Wagner at CRYPTO 2003 for the prevention of probing attacks.

Board-level I/Os signal integrity and conducted EMI have become a critical concern for high-speed circuit and package designers, and a major element of performance and reliability degradation in modern electronic systems, in particular for automotive microcontrollers, which must satisfy stringent low-EMI and noise immunity requirements. One of the most detrimental root causes of I/O signals conducted EMI is the simultaneous switching noise generated by the toggling I/Os (SSO) on the power distribution network of the I/O ring. However, this is not the only noise source that must be considered. In fact, an often overlooked contributor to SSO is the noise generated by the switching digital core that propagates to the I/Os and the noise-sensitive on-chip analog circuitry throughout the common silicon substrate. In this work, we analyze the impact of substrate noise on the I/O signals conducted EMI of an industrial automotive microcontroller, and we compare it against other noise sources. Moreover, we demonstrate the effectiveness of the technological protections against substrate noise in a leading-edge technology. © 2013 ieee.

the paper deals with the problem of test data volume, test application time and on-chip test decompressor hardware overhead of scan based circuits. Broadcast-based test compression techniques can reduce both the test data volume and test application time. Pattern overlapping test compression techniques are proven to be highly effective in the test data volume reduction and low decompressor hardware requirements. this paper presents a new test compression and test application approach that combines both the test pattern overlapping technique and the test pattern broadcasting technique. this new technique significantly reduces test application time by utilizing a new on-chip test decompressor architecture presented in this paper.
