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.
