A Lightweight and Robust Authentication and Key Agreements with Physically Unclonable Function in Manufacturing Environments

Abstract

With the growth of networks and semi-conduction, the Internet of things (IoT) is undergoing a golden year nowadays. At the same time, the Internet of Things (IoT) in the manufacturing environment has faced a critical problem with information security. As the network technology flourish, the way of attack is richer and richer. The traditional defense solution no longer fits with manufacturing environments. Therefore, the industry is willing to get a lighter weight and stronger security mechanism to confront security challenges in the future. In order to achieve the state above, the new mechanism needs to have the ability to generate the truly random value to avoid the collision that the algorithm used now may face, although it seldom happens. Simultaneously, it needs to reduce power consumption as much as possible. Thus, Physically Unclonable Function (PUF) is a solution. Because it has the property which can generate truly random values to avoid collision and save power when executing, our proposed scheme aims to improve the performance and reliability of Physically Unclonable Functions (PUF) to authentication to create a secure channel. When devices in the manufacturing environment transmit a message, it will be bypassed by a secure channel to the destination safely.
