Abstract:
The present invention provides a method for authenticating distributed peripherals on a computer network using an array of physically unclonable functions (PUF). As each PUF is unique, each PUF is able to generate a plurality of challenge response pairs that are unique to that PUF. The integrated circuits of the PUF comprise a plurality of cells, where a parameter (such as a voltage) of each cell may be measured (possibly averaged over many readings). The plurality of cells in the PUF may be arranged in a one, two or more dimensional matrix. A protocol based on an addressable PUF generator (APG) allows the protection of a network having distributed peripherals such as Internet of things (IoT), smart phones, lap top and desk top computers, or ID cards. This protection does not require the storage of a database of passwords, or secret keys, and thereby is immune to traditional database hacking attacks.

Claim (Index 1):
A method for encoding ternary data for a plurality of cells in a physically unclonable function (PUF) that correspond to a response in a challenge response pair, comprising the steps of:\n determining, by an addressable PUF generator (APG), a plurality of cells in a PUF that correspond to a response; measuring, by the APG, a parameter for each cell in the plurality of cells in the PUF that correspond to the response; assigning, by the APG, a zero to each cell in the plurality of cells in the PUF that correspond to the response with a parameter below a predetermined range; assigning, by the APG, an X to each cell in the plurality of cells in the PUF that correspond to the response with a parameter within the predetermined range; and assigning, by the APG, a one to each cell in the plurality of cells in the PUF that correspond to the response with a parameter above the predetermined range.
