This paper proposes a solution for secure data sharing among companies in Industry 4.0, combining attribute-based encryption, blockchain, hardware security modules, and the Interplanetary File System. The solution also includes OpenID for dynamic client identification and a new method for user revocation in attribute-based encryption. Evaluation results demonstrate that the solution can scale up to 2,000,000 clients while maintaining security guarantees.
Collaborative manufacturing is a key enabler of Industry 4.0 that requires secure data sharing among multiple parties. However, intercompany data-sharing raises important privacy and security concerns, particularly given intellectual property and business-sensitive information collected by many devices. In this paper, we propose a solution that combines four technologies to address these challenges: Attribute-Based Encryption for data access control, blockchain for data integrity and non-repudiation, Hardware Security Modules for authenticity, and the Interplanetary File System for data scalability. We also use OpenID for dynamic client identification and propose a new method for user revocation in Attribute-Based Encryption. Our evaluation shows that the solution can scale up to 2,000,000 clients while maintaining all security guarantees.
