Abstract:

This paper proposes a secure and lightweight authentication mechanism, which is signed with the physical unclonable functions (PUF) and finite state machines (FSM), because of the characteristics of low-power and micromation of the Internet of Things (IoT) devices and applications. The model can protect intellectual property (IP) cores from cloning, physical attacks, unauthorized user access, and misuse. The three-level FSM is used to design the authentication with error correction, based on two kinds of hybrid PUF. The goal is to protect IP cores in IoT devices and applications, to reduce the time complexity without using any complex algorithms and huge hardware resources, and to authorize the use. Experimental results show that the lightweight properties such as area and power consumption have obvious advantages compared with existing IP protection.

Key words: internet of things, physical unclonable functions, finite state machines, intellectual property
