PUF-based Authentication Scheme for IoT Devices
Seungyong Yoon, Byoungkoo Kim, Yousung Kang, Dooho Choi · 2020
This paper is about mutual authentication technology between devices with minimal user intervention in a large-scale IoT environment using PUF (Physical Unclonable Function). Most of the existing authentication schemes have been studied focusing only on device-to-server authentication, but the proposed method provides a mutual authentication between devices and devices that utilize the authentication server as a reliable intermediary. We can defend against information leakage, replay attacks, man-in-the-middle attacks, physical attacks, and machine learning based modeling attacks that can occur from various security threats of IoT devices through the proposed method in this paper.
