Secure processes for Industry 4.0
The researchers focused on two risks for secure processes: The threat from hackers to the production process, and the challenge of making a workpiece trackable and identifiable anywhere in the production process. "The idea is to ensure that in case of a production bottleneck alternative routes can be identified. This requires so to speak "navigation systems," explains Oliver Pütz-Gerbig, Product Manager for RFID & Locating at Balluff.
Together with Wubu-Systems, a specialist in protection and licensing of software and documents, Balluff assisted the manufacturer of woodworking machines in this project in constructing secure processes for customized production. Using the example of furniture production, the participants analyzed the individual process steps from product development to product planning and production to service. From this they were able to implement appropriate protection measures and implement them by way of example. To provide for secure communication, the OPC UA protocol with end-to-end encryption is now used in production. This prevents spying on or manipulating data.
