Analytic and Simulation Results of a Gaussian Physically Unclonable Constant Based on Resistance Dispersion
, University of UdineAbstract
Physically Unclonable Constants (PUCs) are a special type of Physically Unclonable Constants and they can be used to embed secret bit-strings in chips. Most PUCs are an array of cells where each cell is a digital circuit that evolve spontaneously toward one of two states, the chosen state being function of random manufacturing process variations. In this paper we propose an Analog Physically Unclonable Constant (APUC) whose output is an analog value to be transformed in digital by a digitizer circuit. The ratio behind this proposal is that an APUC cell has the potential of providing more than one bit, reducing the required footprint. Preliminary theoretical analysis and simulation results are presented. The proposed APUC has interesting performances (e.g., it can provide up to 5 bits per cell) that grant for further investigation.
