NIST Cyber-Physical Systems Public Working Group Kickoff Webinar

What are Cyber-Physical Systems or CPS?

  • Is a CPS any engineered system with a microprocessor?
  • Do all CPS need to be connected to the internet? 
  • Are there a set of basic functions and architectural elements common to all CPS?

You are invited to join us in answering these questions and charting the path to the future.

The Cyber-Physical Systems Public Working Group (CPS PWG) will bring together experts to help define and shape key aspects of CPS to accelerate its development and implementation within multiple sectors of our economy.

Cyber-Physical Systems or "smart" systems are co-engineered interacting networks of physical and computational components. These systems are at the heart of our critical infrastructure and form the basis of our future smart services. These promise increased efficiency and interaction between computer networks and the physical world enabling advances that improve the quality of life, including advances such as in personalized health care, emergency response, traffic flow management, and the electric power generation and delivery. Key stakeholders in CPS have identified the need to develop a consensus definition, reference architecture, and a common lexicon and taxonomy. These will facilitate interoperability between elements and systems, and promote communication across the breadth of CPS stakeholders. As these concepts are developed, it is critical to ensure that timing, dependability, and security are considered as first order design principles. NIST is establishing the CPS PWG to address these challenges.

The four initial workgroups of the CPS PWG will cover (1) Definitions, Taxonomy and Reference Architecture, (2) Use Cases, (3) Timing and Synchronization, and (4) Cybersecurity and Privacy.



The first meeting of the CPS PWG was held on June 30, 2014, 1:00 – 2:30 PM EDT via webinar. The CPS PWG is open to all interested participants and participation is free. Participants must register in advance.

The meeting agenda included an overview of the NIST CPS PWG, working group websites and logistics, and overviews of each of the four subgroups, followed by audience questions and answers and concluding remarks.


The CPS PWG is intended to bring together a diverse set of technical stakeholder communities including industry, academic, and government R&D experts working on existing and planned cyber physical systems.
