Industrial IoT Security Concept with Ex...

Electronic data-sheets that are stored within and provided by a transducer such as ISO/IEC/IEEE 21450 Transducer Electronic Data-sheets are currently intended to ease the utilization of transducers. This is achieved as the data-sheets provide information about sensing and actuation as well as communication capabilities, data formats, calibration information and more. However, so far it can not be ensured that the provided information is trustworthy. Consequently, we propose a concept based on ISO/IEC/IEEE 21450 Transducer Electronic Data-sheets in which signatures and secure elements are used to validate the information in the data-sheets, the manufacturer and calibration labs. Furthermore, this information can be utilised for secure key exchange mechanisms and permission management. This approach ensures that the low-power consumption expected of transducers is still met while providing security and trust.
