Using Blockchain-IPFS to Ensure Data Integrity in Arezzo-Flexible Manufacturing System

The Fourth Manufacturing Revolution is a new phase of the Industrial Revolution, emphasizing the Internet of Things (IoT) and cyber-physical systems. It combines manufacturing and physical operations with smart digital technologies such as security, machine learning and big data to create a connected, improved and more efficient ecosystem for manufacturing applications. Based on the three basic requirements of smart manufacturing systems and Industry 4.0 which are intelligence, sustainability and security; the security aspect becomes a key element of the challenge for the creation of this last ecosystem. This work presents an approach for using blockchain to secure intelligent flexible manufacturing systems. The objective of this proposed approach is to secure communications between AREZZO-FMS workstations by automatically verifying the integrity of these communications generated and to apply traceability using the IPFS system and Ethereum blockchain technology.
