Abstract
The open and cooperative nature of cyber-physical systems (CPS) poses a significant new challenge in assuring dependability. A European-funded project named DEIS addresses this important and unsolved challenge by developing technologies that facilitate the efficient synthesis of components and systems based on their dependability information. The key innovation that is the aim of DEIS is the corresponding concept of a Digital Dependability Identity (DDI). A DDI contains all the information that uniquely describes the dependability characteristics of a CPS or CPS component.
In this paper we present an overview of the DDI and provide the protocol for ensuring the security of the DDI while it is in transit and rest. Additionally, we provide confidentiality, integrity, and availability validation of the protocol.
