Abstract: Physically Unclonable Functions (PUFs) are essential to secure IoT systems through facilitating authen- tication and secure key exchange in IoT infrastructure systems. Authentication and secure key exchange form the basis for all other facets of system security. In IoT infrastructure systems the weakest link in the system is the edge devices since they are located in unsecured locations and have limited processing and energy resources. Implementing PUFs in IoT edge devices is an inexpensive solution that endows the edge device with unique fingerprints (unique ID), immunity to tampering, reverse engineering, counterfeiting and session keys that can not be hacked or duplicated. In this presentation we will review the five most commonly used PUFs and how their performance can be analyzed. We also review the basic algorithm used for authentication and secure key exchange. We then propose two more powerful algorithms that provide more security.
