Ontology-Based Reasoning about the Trustworthiness of Cyber-Physical Systems



Edward R. Griffor, David A. Wollman, Martin J. Burns, Claire Vishik, Michael Huth, Marcello Balducinni


It has been challenging for the technical and regulatory com-munities to formulate requirements for trustworthiness of thecyber- physical systems (CPS) due to the complexity of theissues associated with their design, deployment, and opera-tions. The US National Institute of Standards and Technology(NIST), through a public working group, has released a CPSFramework that adopts a broad and integrated view of CPS andpositions trustworthiness among other aspects of CPS. This pa-per takes the model created by the CPS Framework and itsfurther developments one step further, by applying ontologi-cal approaches and reasoning techniques in order to achievegreater understanding of CPS. The example analyzed in the pa-per demonstrates the enrichment of the original CPS model ob-tained through ontology and reasoning and its ability to deliveradditional insights to the developers and operators of CPS.
