A Hybrid Architecture for Secure Management of Manufacturing Data in Industry 4.0
Anku Adhikari, Marianne Winslett · 2019
In this paper, we analyze the suitability of the methods available today for securely managing the wide variety of data produced by the manufacturing sector. We propose a hybrid information architecture for manufacturing, based on decentralized blockchains, cloud-based WORM storage and ordinary cloud storage. We point out shortcomings in the technology available today for realizing this architecture. In particular, we identify a need for low-cost IoT-based systems to capture, identify, preprocess, encrypt and transmit factory floor data to the corresponding data storage subsystems. We describe our proof-of-concept implementation of such an IoT system, along with the factory case study that inspired it, and argue that this system is sufficiently inexpensive to be retrofitted into today's factories.
