Title
Stability Analysis Of A Physical Unclonable Function Based On Metal Resistance Variations
Abstract
Keying material for encryption is stored as digital bitstrings in non-volatile memory on FPGAs and ASICs in current technologies. However, secrets stored this way are not secure against a determined adversary, who can use probing attacks to steal the secret. Physical unclanable functions (PUFs) have emerged as an alternative. PUFs leverage random manufacturing variations as the source of entropy for generating random bitstrings, and incorporate an on-chip infrastructure for measuring and digitizing the corresponding variations in key electrical parameters, such as delay or voltage. PUFs are designed to reproduce a bitstring on demand and therefore eliminate the need for on-chip storage. In this paper, we evaluate the randomness, uniqueness and stability characteristics of a PUT based on metal wire resistance variations in a set of 63 chips fabricated in a 90 nm technology. The stability of the PUT and an on-chip voltageto-digital converter are evaluated at 9 temperature-voltage corners.
