Blockchain-Enabled Key Generation Using Physical Unclonable Function for IoT Security

Abstract

The security issue is receiving a lot of interest from researchers and providers due to the ubiquitous nature of the Internet of Things (IoT) in many different domains. The Internet of Things is a centralized system with significant limitations, including low memory capacity and limited processing power. As a result, this restriction prevents the use of conventional security methods to shield devices from identity theft and enable safe data transfer over the Internet of Things. Therefore, a new scheme is proposed to provide the security mechanism. To cover this issue, Blockchain technology is adopted in this approach to define a decentralized Internet of Things system which offers security features like transparency, tractability, etc., and where IoT is identified by assigning a unique identity and key generation application through the use of use of a hardware security primitive called a Physical Unclonable Function. This paper offers a Blockchain-enabling key generation via Physical, Unclonable Function.
