A framework for trustworthiness assessment based on fidelity in cyber and physical domains

TL;DR

This paper presents a framework for assessing trustworthiness in open systems by measuring fidelity between cyber and physical domains, using a MAPE loop to monitor compliance and ensure safety.

Contribution

It introduces a novel method for trust assessment based on fidelity measurement and implements a prototype architecture with a MAPE loop for monitoring and action planning.

Findings

Developed a fidelity-based trust assessment framework

Implemented a prototype with a MAPE loop for compliance monitoring

Demonstrated potential for enhancing system safety and resilience

Abstract

We introduce a method for the assessment of trust for n-open systems based on a measurement of fidelity and present a prototypic implementation of a complaint architecture. We construct a MAPE loop which monitors the compliance between corresponding figures of interest in cyber- and physical domains; derive measures of the system's trustworthiness; and use them to plan and execute actions aiming at guaranteeing system safety and resilience. We conclude with a view on our future work.
