Physically Unclonable Function (PUF) Hardware Arrangement for Increased Throughput

Description

The technology provides a method for authenticating distributed peripherals (e.g., smartphones, laptops, and the Internet of Things) on a network, using physical unclonable functions (PUFs) in an array. This architecture increases the system’s bandwidth by taking advantage of the host (H) and addressable PUF generator (APG) scalability. Bandwidth increases almost proportionally with the number of H/APG systems. In turn, the technology uses an array of components built with physical elements and a router to increase the bandwidth and throughput.

Potential applications

This technology is designed for use with cryptographic systems and authentication methods.

Benefits and advantages

A memory array can be a very economical way to design a large array of physically unclonable functions (PUFs) at different addressable locations. In the matrix, the plurality of host (H) and addressable PUF generator (APG) is configured so that two or more H/APGs operate at the same or overlapping times, greatly increasing the speed and efficiency of the invention.
