Abstract
Advancements in cyber–physical systems (CPSs) makes CPSs essential entities in society today, and have made them prominent across all fields. For example, the healthcare industry has evolved technologically and has effectively incorporated CPS into many application areas. While these advancements, involving medical CPSs (MCPS), have been revised according to Society 4.0, there are still issues that need to be considered while we transition from an information-based society (Society 4.0) to a human-centric society (Society 5.0). In this article, we propose an MCPS framework for Society 5.0 in the context of some state-of-the-art technologies. The proposed system focuses on enhancing security aspects of Society 5.0 through introduction of a security layer equipped with protocols, such as open authorization (OAuth), user-managed access (UMA), and self-sovereign identity (SSI). The added security layer is designed to incorporate country-specific security laws. Challenges and design issues in developing a trusted and secure service for MCPS are also discussed using vulnerability assessment and attack modeling. Finally, we discuss ethical aspects that need to be addressed in the transition from Society 4.0 to Society 5.0.
