Secure Automation Frameworks for Smart Manufacturing Using Blockchain-Assisted Traceability

Abstract

Smart manufacturing systems depend on automation and machine interconnection and real-time data exchange to achieve their goals of enhancing operational efficiency and boosting production output. The system's wide-ranging connections lead to significant challenges which disrupt security systems and data protection measures and create problems for different stakeholders to establish system trustworthiness. Centralized security systems which protect methods through their centralized security systems fail to prevent unauthorized access while they fail to safeguard data from unauthorized alterations and track operations in industrial environments. Blockchain technology maintains secure data storage through its permanent record system and cryptographic security features which make it an effective solution to this problem. Smart manufacturing research develops a secure automation system which combines blockchain-based traceability systems with industrial automation technology. The system protects data during transmission while it generates permanent records of all transactions which allow complete visibility of manufacturing operations throughout the supply chain. The proposed system uses smart contracts to perform automated verification of compliance requirements and control system access and validate operational processes without needing any central governing body. The system enables organizations to work together better because it establishes trust between all parties while safeguarding their business operations. The research demonstrates that blockchain-based traceability systems provide enhanced cybersecurity protections which create accountable systems that enable automated processes to function in modern manufacturing environments which use Industry 4.0 technologies.
