CPS PWG Subgroups

Reference Architecture

  • Vocabulary and Reference Architecture Subgroup

This subgroup will develop a common CPS vocabulary, including a working definition of CPS and descriptions of common features, capabilities, and characteristics, to inform the development of CPS reference architecture(s) and to promote communications across CPS stakeholders and domains. The reference architecture development will include the identification of foundational goals, characteristics, common roles, actors, and interfaces, across the breadth of CPS domains. The reference architecture will be designed to include applicable cybersecurity and privacy considerations. The current NIST draft notional CPS reference architecture will serve as one source of input to this working group.

Reference Architecture Co-Chairs

Use Cases Subgroup

  • This subgroup will identify CPS use cases, both current and envisioned, in specific sectors, domains, and applications to understand how actors within CPS systems will interact and provide input on functional requirements to the reference architecture subgroup. The use cases will be used to identify and evaluate common CPS characteristics, actors, interfaces, and associated applied cybersecurity objectives and considerations.

Timing and Synchronization Subgroup

  • This sub-group includes an existing organization, Time Aware Applications, Computers and Communications Systems (TAACCS), led by NIST. This subgroup will ensure that the Reference Architectures, and the Use Cases have appropriate timing and synchronization considerations. The timing and synchronization subgroup will evaluate the timing needs and explore what research needs to be done and optimal directions to satisfy those needs.

Cybersecurity and Privacy Subgroup

  • Although CPS encompasses a broad and diverse range of sectors, domains, and applications, it is uniformly expected that cybersecurity and privacy considerations must be included in all phases of the system development lifecycle, from design through implementation, maintenance, and disposition. The primary goal of the Cybersecurity and Privacy subgroup is to develop a cybersecurity and privacy strategy for the common elements of CPS that includes a focus on the identification, implementation, and monitoring of specific cybersecurity activities (including the identification, protection, detection, response and recovery of CPS elements) and outcomes for CPS in the context of a risk management program. Where applicable standards, guidelines, and measurement metrics do not exist, this subgroup will identify areas for further CPS cybersecurity research and development.

Data Interoperability Subgroup

  • This subgroup will address the simplification and streamlining of cross-domain data interactions by developing a sound underlying framework and standards base for CPS data interoperability, in part by developing an inventory of relevant existing practices and standards. There are many CPS domains in which data is created, maintained, exchanged, and stored. Each datum has a data flow and a life cycle. Each domain naturally defines its own data semantics and exchange protocols, but those data can be difficult to understand and process when moved across domains and ownership boundaries, an increasing requirement of an increasingly connected world. This is as much, if not more so, the case in cyber physical systems as it is in other data management domains. This subgroup will address these cross-cutting data interoperability issues and point the way to the develop of new efficient and scalable approaches to managing CPS data.
