Blurry Box Encryption Scheme and Why it Matters to Industrial IoT
5.5 USE CASE: INDUSTRIE 4.0
Industrie 4.0 9 can only take off if holistic and sustainable security architectures with software protections are implemented. The increasing number of networked devices is a magnet for cyberattackers ready to exploit vulnerabilities and manipulate production processes to cause massive damage or seize technical know-how. The opportunity to test preventative measures at SmartFactory KL, a leading competence center and manufacturer-independent demonstration and research platform, delivered great results for all manufacturing vendors.
The flexible production line designed according to Industrie 4.0 principles at SmartFactory KL has been upgraded with added security. Software protections have been applied to the connected IoT and cyber-physical systems that form part of the facilities. Cryptographic keys for secure communication with open standard OPC UA are stored securely in secure elements. The product data used in the production process and stored in RFID tags is secured by digitally signing the data on the tags. Its integrity is protected from the tag to the cloud or vice versa and verified with tablet computers on the shop floor. This ensures that the production line only accepts valid production data from authorized parties.
5.6 USE CASE: IOT INDUSTRY
Microcontrollers are the heart of some of today’ s IoT devices: Small, energy-efficient systems that implement the algorithms and features for sensors, actuators, motor controls, and more. They communicate via open networks and need appropriate protection. The chapter, Protecting Endpoints, of the IIC’ s Industrial Internet Security Framework( IISF) describes these requirements: Software protection, which is a must, is the basic vehicle for truly secure IoT devices. To facilitate this, makers of microcontroller and semiconductor integrate protection mechanisms in their development tools and offer secure boot strap loaders. This allows production volume controls, secure, tamper-proof firmware downloads and updates as well as flexible feature licensing. IoT / IIoT devices using such features include different sensors with intelligent preprocessing and network interfaces, intelligent RFID-readers with OPC UA communication, pumps, actuators, valves, or intelligent grippers. Manufacturers benefit from lower logistics costs due to unified production and feature configuration during final tests or even at the customer. After-sales business will be created with the app-store concept known from the consumer market. Licensing is key to new monetization mechanisms in today’ s digitization.
5.7 USE CASE: AUTOMATION INDUSTRY
Modern machines communicate hierarchically with Manufacturing Execution Systems( MES) and Enterprise Resource Planning( ERP) systems. Integrated robots contain PLCs and multiple intelligent servo mechanisms. A milling machine has a PLC and a set of sensors and actuators.
