Efficient Integration of Secure and Safety Critical Industrial Wireless Sensor Networks
Wireless communication has gained more interest in industrial automation due to flexibility, mobility, and cost reduction. Wireless systems, in general, require additional and different engineering and maintenance tasks, for example cryptographic key management. This is an important aspect that needs to be addressed before wireless systems can be deployed and maintained efficiently in the industry. In this paper, the authors take an holistic approach that addresses safety and security regardless of the underlying media. In their proposed framework, they introduce security modules which can be retrofitted to provide end-to-end integrity and authentication measures by utilizing the black channel concept.
