Software Unclonable Functions for IoT Devices Identification and Security

TL;DR

This paper explores the use of software unclonable functions derived from hardware performance counters to enhance IoT device identification and security, addressing the challenge of distinguishing legitimate devices from compromised ones.

Contribution

It introduces the concept of software unclonable functions (SUFs) based on HPC signatures for IoT security, a novel approach in device authentication.

Findings

HPC-derived signatures are unique for individual IoT devices.

SUFs can effectively differentiate between legitimate and compromised devices.

The approach enhances IoT security through hardware-based unclonable identifiers.

Abstract

In the evolving landscape of IoT ecosystem, distinguishing between legitimate and compromised devices is a critical challenge. This research investigates the effectiveness of hardware performance counter (HPC)-derived signatures' uniqueness under the umbrella of a concept that we introduced as software unclonable functions (SUFs).
