Towards an Architectural Framework and Method for Realizing Trustworthy Complex Cyber-Physical Systems

Cyber-Physical Systems (CPS) are evolving to become smarter, more autonomous, connected and collaborating. Provided with unprecedented capabilities, the CPS also represent unprecedented complexity and bring new risks that go beyond classical dependability. This paper outlines a framework for complex CPS with the purposes to facilitate holistic considerations of trustworthiness and its various attributes. The framework addresses trustworthiness from both technical (e.g., safety, reliability and security, etc.) and social perspectives (e.g. w.r.t. ethics, transparency and privacy). The framework is not intended primarily to replace existing CPS frameworks, but rather to complement them by providing an approach for incorporating trustworthiness considerations as a first class citizen. The workflow for the proposed framework is presented and we briefly outline its application to two use cases in the domain of intelligent transportation systems.QC 20221201TECoSA and InSecT
