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.}, organization = {European Union’s Horizon 2020, 871518}, publisher = {MDPI}, keywords = {Industrial Internet of Things}, keywords = {Access control}, keywords = {Blockchain}, keywords = {Attribute-based encryption}, keywords = {Revocation}, keywords = {Data-sharing}, keywords = {Industry 4.0}, title = {Fine-Grained Access Control with User Revocation in Smart Manufacturing}, doi = {10.3390/electronics12132843}, author = {Gómez Marín, Ernesto and Martintoni, Davide and Senni, Valerio and Castillo Morales, María Encarnación and Parrilla Roure, Luis}, }
