Abstract

This paper presents a framework for securing blockchain-based IoT systems by integrating Physical Unclonable Functions (PUFs) and Zero-Knowledge Proofs (ZKPs) within a Hyperledger Fabric environment. The proposed framework leverages PUFs for unique device identification and ZKPs for privacy-preserving authentication and transaction processing. Experimental results demonstrate the framework's feasibility, performance, and security against various attacks. This framework provides a comprehensive solution for addressing the security challenges in blockchain-based IoT systems.
