A Blockchain-based Three-factor Mutual Authentication System for IoT using PUFs and Group Signatures

The widespread adoption of Internet of Things has brought many benefits to society, such as increased efficiency and convenience in various aspects of daily life. However, this has also led to a rise in security threats. Moreover, resource-constrained feature of IoT devices makes them vulnerable to various attacks that compromise the user's privacy and sensitive information confidentiality. It is therefore essential to address the security concerns of IoT devices to ensure their reliable and secure operation. This paper proposes a blockchain-based three-factor mutual authentication system for IoT using Elliptic Curve Cryptography, physical unclonable functions and group signatures. The main purpose is to achieve a secure mutual authentication among different involved entities while providing anonymous group member authentication and reliable auditing. The AVISPA tool is utilized in the paper to formally prove that the proposed system satisfies the security and privacy requirements.
