CPS Public Working Group

NIST Cyber-Physical Systems Public Working Group

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

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.

Subgroups and Meetings

The CPS PWG will be composed of five initial sub-working groups:

Participants may choose to be members of one or more sub-groups. The NIST CPS PWG Sub-Groups will meet virtually approximately bi-weekly, and also may have additional face-to-face meetings. The initial kickoff webinar meeting of the combined CPS PWG was held on June 30, 2014, and the initial face-to-face meeting (live link to the webpage ) of the combined CPS PWG was held on August 11-12, 2014.
