Hardware Support for Authentication in Cyber Physical Systems

The efficiency and benefit of Cyber Physical Systems (CPS) depend heavily on interconnection of individual devices or nodes. Exchange of data, information relevant to an overall task or functionality is the key to many applications such as smart grids, smart cities, and many others. Trustworthiness of data is needed to make such systems successful. To be able to fulfill policies to guarantee the safety of all entities within a CPS and to provide security measures to enforce these cryptographic solutions have to be embedded. As we show in this paper it is possible to integrate security building blocks in ultra-small devices to provide essential properties for secure embedded systems. With proper policies, high cryptographic standards, rising acceptance by users, and provable security and safety measures, CPS will open countless possibilities to increase efficiency in many aspects of our everyday lives.
