Standardized Trust Model for Data Security in Smart Systems

This technical report presents a standardized trust model aimed at enhancing data security and interoperability within smart distributed systems (SDS). SDS are integral to modern economies, facilitating data exchange across various sectors such as energy, transportation, and healthcare. The report outlines the critical characteristics of SDS, including cyber-physical integrations, heterogeneous entities, and hyperconnectivity. It emphasizes the necessity for secure collaboration and proposes a global standard that encompasses security, interoperability, and authentication. The document specifically focuses on distributed energy ecosystems (DEE) as a case study, detailing their dynamic nature and the need for robust signaling systems. The proposed trust model is organized into four layers, addressing concerns such as key management and resource protection. The report concludes that effective interoperability and security are essential for the operational integrity of DEEs, particularly in the face of evolving cyber threats.
